Question

What size in the hypotenuse of the right angle of the television screen shown in the illustration? Find if d if a=20in, and b=15

a.50 in.
b.13.2 in.
c.14.2 in.
d.25.0 in.

Answer 1

Answer:

The correct option is D) 25 in.

Step-by-step explanation:

Consider the provided information.

It is given that the a = 20in, and b = 15 in.

Now use the Pythagorean theorem $a^2+b^2=c^2$

Where a and b are two sides and c is the hypotenuse.

Substitute the respective values in the above formula.

$(20)^2+(15)^2=c^2$

$400+225=c^2$

$625=c^2$

$\pm25=c$

Neglect the negative value as side cannot be a negative number.

$25=c$

Hence, the size of hypotenuse of the television screen is 25 in.

Therefore, the correct option is D) 25 in.
