Answer:

Hence,

The measure of ∠A is 60.065°

\m\angle A= 60.065

Step-by-step explanation:

Given:

ΔABC is a Right Angle Triangle at ∠ B = 90°

BC = Opposite side to ∠A = 13 unit

AC = Hypotenuse  = 15 unit  

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\\\angle A=\sin^{-1}(0.8666)\\m\angle A= 60.065\°

Hence,

The measure of ∠A is 60.065°

\m\angle A= 60.065

jok3333 [9.3K]
The answer is <span>length = 10 yd, width = 2 yd
proof 
</span><span>The length of the playground is 5 times longer than its width, it means
l=5w, but 10= 2x5 so we can write l= 5w, 
and Area = 20 =l x w = (5x2) x 2 =20</span>
