The hypotenuse of a triangle measures 12 inches, and the measure of one of the acute angles is two less than three times the measure of the other acute angle. What is the area of the triangle? Round your answer to the nearest square inch. (Note: The area of a triangle is 1/2bh, where the base and the height of the triangle are perpendicular).
Answer:
26 sq in.
Step-by-step explanation:
Let x = measure of one acute angle
3x - 2 = measure of other acute angle
Since the triangle is a right triangle, the sum of the measures of the acute angles is 90
x + 3x - 2 = 90
4x - 2 = 90
4x = 92
x = 23
90 - 23 = 67
The acute angles are 23° and 67°
Now, let a = length of side opposite the 23° angle
sin 23 = a/12
a = 12 sin 23
Let b = length of the side opposite the 67° angle
sin 67 = b/12
b = 12 sin 67
Area = 1/2ab = 1/2(12 sin 23°)(12 sin 67°)
= 25.90
26 sq in to the nearest inch
Wow! That is quite the problem.
IN EFG the measure of G=90 DG=21 feet and EF=63 feet find the measure of E to the nearest degree.
Answer:
19.5°
Step-by-step explanation:
IN EFG the measure of G=90 DG=21 feet and EF=63 feet find the measure of E to the nearest degree.
We solve the question using Sine rule
= a/sin A = b/sin B
= 21/sin E = 63/sin 90
Cross Multiply
Sin E × 63 = 21 × sin 90
sin E = 21 × sin 90/63
E = arc sin( 21 × sin 90/63)
E = 19.47122°
Approximately = 19.5°
When 6 is added to the difference between 4 times a number and 7, the result is greater than 14 added to 3 times the number. Find all such numbers.
Answer: x > 15
Step-by-step explanation:
Let the number be represented by x. Based on the information given, we can form an equation as:
(4x - 7) + 6 > 3x + 14
4x - 7 + 6 > 3x + 14
4x - 3x > 7 - 6 + 14
x > 15
Therefore, x include numbers such as 16, ....

Two hammers and a screwdriver cost a total of 34. A hammer and 3 screwdrivers cost a total of 32. Find the price of each type of tool
Answer: 14 , 6
Step-by-step explanation:
Given
2 hammers and a screwdriver cost 34
1 hammer and 3 screwdrivers cost 32
Suppose the cost of the hammer is x and the cost of the screwdriver is y
[tex]\therefore 2x+y=34\quad\ \ldots(i)\\x+3y=32\quad \ldots(ii)[/tex]
Solving (i) and (ii) we get
[tex]x=14;y=6[/tex]
Thus, hammer cost 14 and screwdriver costs 6

Answer:
The Answer Is E!
Step-by-step explanation:
To solve this equation., you have to try every solution and the only one that perfectly completes both statements is answer E.
We subtract the $1.15 from $2.10 if this is the price of one taco, leaving the price of a small cup of coffees price ($2.10-$1.15=$0.95 for a small cup of coffee
To check it fits both statements, we multiply the price of one coffee by 3 ()$0.95×3=$2.85 for three small coffees\
Next, we multiply $1.15 (one taco) by 2 to fill in the expression ($1.15×2=$2.30)
Finally, we add both the prices of the 3 coffees and two tacos which adds up to a perfect $5.15, justifying the answer

The area of shaded and unshaded sector is 1.13 × P^2 and 1.99 × P^2.
How to find the surface area of some object?
Find the area that its outer surfaces possess. Sum of all those surfaces' area is the surface area of the considered object.
Suppose that radius of the considered sphere is of 'r' units.
Then, its surface area S would be:
[tex]S = 4\pi r^2 \: \rm unit^2[/tex]
We are given that;
P is the center, angle LPJ=130degree
Now,
To find the approximate values, we can use 3.14 for π and round to the nearest tenth:
Area of shaded sector = (13π/36) × P^2
≈ (13 × 3.14/36) × P^2
≈ 1.13 × P^2
Area of unshaded sector = (23π/36) × P^2
≈ (23 × 3.14/36) × P^2
≈ 1.99 × P^2
Therefore, by the surface area the answer will be 1.13 × P^2 and 1.99 × P^2.

Caleb has 3 packs of colored pencils. Each pack has x pencils in it. After Ryan gives him 6 more
colored pencils, he has a total of 27 pencils.
Answer:
3 × x + 6 = 27 - 6 = 21 divided by 3 = 7 so 7 pencils in each box. 6 divided by 3 = 2 which means 7 + 2 = 9 pencils in the box total after Ryan gives 6 pencils to caleb.

Find the area of trapezoids
Answer:
Area is 10.5
Step-by-step explanation:
We can use the trapezoid formula of
[tex]A = \frac{a+b}{2}h[/tex]
A = (2 + 5) / 2 * 3 = 3.5 * 3 = 10.5
or break it into a rectangle and a triangle (natural split by y axis).
A = 2 * 3 + 3 * 3 / 2 = 6 + 9 / 2 = 6 + 4.5 = 10.5
Answer:
10.5 units²
Step-by-step explanation:
The area (A) of a trapezoid is calculated as
A = [tex]\frac{1}{2}[/tex] h (b₁ + b₂ )
where h is the perpendicular height and b₁, b₂ the parallel bases
Here h = OS = 3 , b₁ = OC = 5 , b₂ = SK = 2 , then
A = [tex]\frac{1}{2}[/tex] × 3 × (5 + 2) = 1.5 × 7 = 10.5 units²
