X = 152.
Figure out the angles of the insides of the triangle and then you'll have your answer:
First angle = (supplementary) 180 - 85 = 95
Second angle = (supplementary) 180 - 123 = 57
95 + 57 = 152
152 = the measure of angles one and two
Find the third angle
180 - 152 = 28
Angle x and angle three (28) are supplementary angles so subtract to find x:
180 - 28 = 152
Answer:
1
Step-by-step explanation:
x² + 5x-5
Let x = -6
(-6)^2 + 5(-6) -5
36 -30 -5
6-5

Answer:
yes correct
Step-by-step explanation:
Answer:
Line 1 2y = 8x + 6 y = 8/2 x + 6 = 4 x + 6 slope = 4
Line 3 4x - y = 5 y = 4 x -5 slope = 4
Step-by-step explanation:
y = mx + b m: slope
Line 1 2y = 8x + 6 y = 8/2 x + 6 = 4 x + 6 slope = 4
Line 3 4x - y = 5 y = 4 x -5 slope = 4
parallel lines have same slope
Combine like terms
the 6s cancel each other out so you just have 11. add -5a to -4a to get -9a
answer should be 11- 9a
