Answer:
The measures of the angles are 150° and 30°.
Step-by-step explanation:
Let x and y represent the measures of the angles, with x representing the larger angle.
x + y = 180 . . . . . . the two angles are supplementary
x = 90 + 2y . . . . . one is 90° more than twice the other
___
Substituting the expression given by the second equation into the first, we have ...
(90 +2y) +y = 180
3y = 90 . . . . . . . . . . collect terms, subtract 90
y = 30 . . . . . . . . . . . divide by the coefficient of y
x = 180 -y = 150
The measures of the angles are 150° and 30°.

let's recall that an isosceles triangle has two twin sides.
Check the picture below.
Answer:
The answer is z = 34.
Step-by-step explanation:
1) Simplify 2 + 8 - z to 10 - z.
2) Subtract 10 from both sides.
3) Simplify - 24 - 10 to -34.
4) Multiply both sides by -1.

Answer:
y = 17x - 55
Step-by-step explanation:
Convert the coordinates in point-slope form:
y + 4 = 17(x -3)
y + 4 = 17x - 51
Subtract 4 in both sides:
y = 17x - 55
