∠C = ∠ D (vertical angles
C= -2x + 90
D= x-30
Since C = D , Then -2x + 90 = x-30
-2x - x = - 30 - 90
-3x = -120
3x = 120 and x = 40°. Now replace x by 40 in any of the equality, say :
D = x-30 ; D = 40 - 30 and D = 10°
10-2(x+4)=14-2x. hope it helps
Answer:
Im gonna go with A
Step-by-step explanation:
Answer:
B)-1/4
Step-by-step explanation:
f(x) = 4x ; slope is 4
perpendicular , slope is opposite and reciprocals so slope of this perpendicular line is -1/4
Answer
B)-1/4
