You are trying to solve for y (get y by itself)

9y + 10 = -8 Subtract 10 on both sides

9y + 10 - 10 = -8 - 10

9y = -18 Divide 9 on both sides

y = -2

In triangle XYZ, the measure of angle X is 84, the measure of angle Y is (r + 59) and the measure of angle z is (r + 51), find t

xenn [34]

Answer:

r = -7
Y = 52°

Step-by-step explanation:

The sum of the measures of the angles in a triangle is 180°.

X + Y + Z = 180°

84° +(r +59)° +(r +51)° = 180°

2r +194 = 180 . . . . . . . . . divide by ° and simplify

2r = -14 . . . . . . . . . . subtract 194

r = -7

Then the measure of Y is ...

Y = (r +59)° = (-7 +59)°

Y = 52°

<em>Additional comment</em>

Z = 44°
