Answer:
53thst is the right. answer
If vertex angle is 42, and the base angles are congruent, this is an isosceles triangle, they each measure: 180-42/2. They each measure 69 degrees. The length of sides don't matter.
Thank you for asking this question. Here is your answer:
M = y2 - y1/x2 - X1 = M
= 290 - 210/120 - 80
M = 80/40
M = 2
Now we will consider y intercept
y = mx + b
210 = 2(80) + b
210 = 160 + b
b = 210 - 160
= 50
Now we will combine everything in order to get the answer.
y = 2x + 50
y = 2(60) + 50
y = 120 + 50
y = 170
So the final answer for this question is $170.
