Answer:
no
Step-by-step explanation:
every triangles degrees equal 180.
78+21=99
180-99=81
the smaller triangle
21+80= 101
180-101=79
so the degrees are different
The z or t score to be used is (0.422,0.978)
How to find the critical value ?
Critical probability (p*) = 1 - (Alpha / 2), where Alpha is equal to 1 - (the confidence level / 100), is the unit statisticians use to determine the margin of error within a set of data in statistics.
The critical value for α = 0.13 is
The corresponding confidence interval is computed as shown below


CI = (0.422, 0.978)
0.422< mu1 - mu 2 < 0.978

Y intercept is (0,-7). slope is 2.
Change the function to y=mx+b format first. m=slope and plug in 0 as x to get y intercept.

I’m pretty sure it’s 60 because if you look at angle 1 is next to the angle that measures 120 degrees and 60+120= 180
