Tell whether the angles are complementary or supplementary. Then find the value of x.
Paha777 [63]
The angles are complementary meaning they =90 degrees.

So take (x-20) and x, and write this equation,

x-20+x=90

2x-20=90

move the 20 over

2x-20=90
    +20  +20

2x=110

x=55.

You can check it by plugging it back in,

(55-20)=35
and
x=55

35+55=90.

Thus, you know your answer is correct.

1 . The lengths of the legs of a right triangle are 25 cm and 60 cm. What is the length of the hypotenuse?
Svetlanka [38]
a^{2}+ b^{2} = c^{2} that is, hypotenuse.
Therefore, let the length of the hypotenuse be 'x.' 
25^{2}+ 60^{2}= x^{2}
625+3600=x^{2}
4225=x^{2}
Therefore,
\sqrt{4225}=x
65=x
The length of the hypotenuse is B.65 centimetres.
