{SOLVE FOR X} ☟︎︎︎
19) 21x + b = 90*(degree)
ANSWER ➪ x =4
20) 11x - 2 = 75*(degree)
ANSWER ➪ x = 7
^ note; if two lines are parallel, corresponding angles are equal.
21) 8x-4 = 60*(degree)
8x = 64
ANSWER ➪ x = 8
^note; two straight line are parallel and the internal stagger angle is equal.
22) x + 139 = 132*(degree)
x= 132- 139
ANSWER ➪ x= -7
^note; two straight lines are parallel and the internal stagger angle is equal.
23) 1 + 14x =12x + 17
2x = 16
ANSWER ➪ x = 8
24) 23x -5 = 21x + 5
2x + 10
ANSWER: x = 5
{Find the measure of the angle indicated in bold}☟︎︎︎
25) x + 96 + x + 96 = 180*(degree)
2x = -12
X = -6
X+ 96 = -6 + 96 = 90*(degree)
ANSWER: 90*(degree)
26) 20x + 5+ 24x - 1 = 180
44x = 180 -4
44x = 176
x= 4
ANSWER: 4
27) 6x = 5x +10
(6- 5)x = 10
x= 10
ANSWER: 10
28) x + 109 + x + 89 = 180
2x = 180 - 198
2x = - 18
X= -9
ANSWER : -9
