50 because 80+50+x=180 (inside triangle) x=130 180-130= 50 (angle outside triangle)
Answer:
According to triangle theorems, we know that the interior angles of a triangle equals 180 degrees. Since we know that angle A and angle B are 55 and 30 degrees, all we need to do is add them up and subtract it from 180 degrees to find out the measure of angle C.
55 + 30 = 85 degrees
180 degrees - 85 degrees = 95 degrees (this is the measure for angle C)
Answer:
the first step is wrong
it should be 4(x-4)/(x+1)(x-4) - (x+2)/(x-4)(x+1)
Answer:
x=-5
Step-by-step explanation:
-2x-41=5x-6
-35=7x
-5=x
