Answer:
m=3
Step-by-step explanation:
Use the slope formula to find the slope m
.
m = (y2 -- y1) / (x2 -- x1)
Answer:
∡A = 48°
∡B = 58°
∡BCA = 74°
Step-by-step explanation:
start by finding m∡BCA; this angle is supplementary with ∡BCD and the pair must add up to 180. therefore, m∡BCA = 74°
all three interior angles of a triangle must add up to 180:
74 + 4y + 3y + 22 = 180
96 + 7y = 180
7y = 84
y = 12
substitute '12' for 'y' in 3y + 22 to get 58
substitute '12' for '4y' to get 48
Its relationships is that it's in the thousands place.
vertical angles are equal
so
2x + 24 = 146
2x = 122
x = 61
Answer
A. 61
