Answer:
m<B = 62°
Step-by-step explanation:
Given that ∆ABC is congruent to ∆TUV, it follows that their corresponding angles are equal to each other. Therefore:
m<B = m<U
m<B = (3y + 2)°
m<U = (4y - 18)°
Thus,
3y + 2 = 4y - 18
Collect like terms
18 + 2 = 4y - 3y
20 = y
y = 20
m<B = (3y + 2)°
Plug in the value of x
m<B = 3(20) + 2
m<B = 60 + 2
m<B = 62°
M=1 b=0
For M: Using the formula to find slope y2-y1/ x2-x1 we can select 2 sample points in this case I’ll use (1, 1) and (2, 2). Inserting those into the formula we get 2-1/ 2-1 which, after subtracting, is 1/1 or 1.
B: The point where the line crosses the y-axis is the origin or (0, 0)
10x-20=180 6x+8

10x= 160
/10 /10
x=16
