9 Find the values of r and y. с A 95° B 4x ro D E

Inga [223]

Answer:

x = 18°, y = 167°

Step-by-step explanation:

In right triangle sum of two angles is 90°

4x + x = 90°
5x = 90°
x = 90°/5
x = 18°

Angle y is exterior angle and equals non-adjacent interior angles

y = 4x + 95° =
4*18° + 95° =
72° + 95° =
167°

Simple...

y= $x^{2} -9$

$y= x^{2} -9$

It's quite easy to see $x^{2} = x^{2}$

Thus, any value of x makes the equation true.

Thus, your answer.
