Answer: A. 85 degrees .
Step-by-step explanation:
So the exterior is less then the interior so what ever result can't be larger then 95 degrees. The sum of the three angles of any triangle is equal to 180 degrees. So this triangle is 180 degrees total. 180-53-42 = 85 degrees.
2 (x-20)+2x=38
4x-40=380
4x=420
x=150
The train is 130mph.
So you want to find how much y=8 and how much x=3 so to do that you multipy 8x3 witch =24 so 8x3=24 ope this helps you.
