Answer:
x= (5X+3) DEGREES = 90 degrees (right angle)
5x=90 degrees - 3 degrees =87 degrees
5x÷5 =87 degrees ÷ 5
x=17.4 degrees
we now know our angles x = 17.4 degrees so we can know substitute into the give formula
wxz=5 (17.4)+ 3
wxz =90 degrees
zxy=we know the size of x
zxy=
8 (17.4)-4
zxy=135.2 degrees
Well, I'm not sure since you didn't post the equation but, all you have to do is plug in the number 4 where x is. So for example, say the equation given to you was y=6x+5. Just plug in 4 for x and you get y=6(4)+5, which is y=29.
They are the same angle. congruent means that they are all in the same spot were the numbers line up and these ones do so the answer is that they are all the same angle.
The answer should be 31
(10(3)+8)-(1(3)+4)
(30+8)-(3+4)
= 31
