Engths of Right Triangles Triangle A C B is shown. Angle A C B is a right angle. The measure of angle A is 15°, and the length of side BC is 8. What are the lengths of the other two sides, rounded to the nearest tenth? AC = AB =

AC =29.86 units ; AB=30.91 units

Step-by-step explanation:

We are given with a right triangle ACB. Where <ACB is a right angle and <A is 15 degrees. Length of BC is 8.

Let's make triangle first then we can use trigonometric ratios to find AC and AB.

12

step-by-step explanation:

a triangle's   full angle is 180 degrees so 180 - 156 = 24. 24/2=12

step-by-step explanation:

the ratio of red paint to blue paint is always 9/7. that means that, whatever x's value, (4x+12)/(4x-4) has that same ratio. so, set up an equation and cross-multiply to solve for x:

9/7 = (4x+12)/(4x-4)

9(4x-4) = 7(4x+12)

36x - 36 = 28x + 84

8x - 36 = 84

8x = 120

x = 15
