Pythagoras Theorem:
hipotenuse²=side1²  +side2²

a=is the longest side of the triangle (hypotenuse)
b and c: are the other two sides.

In this case:
hipotenuse²=side₁² + side₂²

side₁=a=16
side₂=b=28

c²=16²+28²
c²=256+784
c²=1040
c=√1040=32.2490....≈32.25

Hey there. 

To solve this problem we have to use the Pythagorean theorem. The longest side of the triangle is called the "hypotenuse". C² is the longest side so it is the hypotenuse . To calculate c² we have to do α² + β² = c². 

Given 

⇒ a² = 16

⇒ b² = 28 

⇒ c² = unknown 

To solve the problem you have to add a² and b². 

a² = 16
<span>b² = 28  
</span>
16² + 28² = c² 

16² = 16 x 16 
28² = 28 x 28

16² = 256
28² = 784

258 + 784 = 1040

a² + b² = 1040

The next step is to find the square root of 1040

√1042 = 32.2490


= <span>32.2490 is rounded to 32.25 
</span>
Answer = (D)
