Answer:

Therefore the measure of∠ A is 60.07.

Step-by-step explanation:

Given:

In Right Angle Triangle ABC

∠ B = 90°

BC = 13   ....Side opposite to angle A

AC = 15  .... Hypotenuse

To Find:

m∠A = ?

Solution:

In Right Angle Triangle ABC ,Sine Identity,

\sin A = \dfrac{\textrm{side opposite to angle A}}{Hypotenuse}\\

Substituting the values we get

\sin A = \dfrac{BC}{AC}=\dfrac{13}{15}=0.8666\\\\A=\sin^{-1}(0.8666)=60.065\\\\m\angle A=60.07\°

Therefore the measure of∠ A is 60.07

How do i solve this step by step? i dont know how to set up this equation.
zmey [24]

Answer:

Step-by-step explanation:

The two long sides on the left and right and bisected into two equal parts each

That means that since there is an angle in common to the top little triangle and the whole diagram, the little triangle on top and the whole triangle are similar.

The ratio of similarity is 1/2

10/(5x + 5) = 1/2                              Cross multiply

(5x + 5)*1 = 10*2

5x + 5 = 20                                     Subtract 5 from both sides

5x = 20 - 5                                     Combine

5x = 15                                            Divide by 5

5x/5 = 15/5

x = 3

It is.
Notice that 0.127=127/1000, which is obviously a rational number.
