The angles are 27°, 27° and 126°
let the 2 equal angles be x then the third angle = 3x + 45
sum of 3 angles = x + x + 3x + 45 = 5x + 45 = 180
hence 5x = 180 - 45 = 135⇒ x= 135/5 = 27
the angles are 27°, 27° and 3x + 45 =81 + 45 = 126°

Answer:
1. y = -10x + 6
2. y = -x - 6
3. y = 13x + 110
4. y = -5x + 47
5. y = 7/4 x -7
Step-by-step explanation:
2. m = - 1 and Y-intercept: -20 - (- 1)(14) = -6
3. m = 13 and Y-intercept: -7 - (13)(- 9) = 110
4. (10,-3) and (7,12)
Slope = (12 - - 3)(7- 10) = 15/-3 = -5
y- intercept = 12 - (-5)(7) = 47
5. (4,0) and (0, -7)
Slope: (-7-0)/(0-4) = -7/-4 = 7/4
y-intercept: -7 - 7/4)(0) = -7

Step-by-step explanation:
Answer:
z = 38
Step-by-step explanation:
The sum of the angles of a triangle add to 180
z+ 90+52 = 180
Combine like terms
z +142 = 180
Subtract 142 from each side
z+142-142 = 180-142
z =38
