Wait, what are you trying to ask?
Answer:
Step-by-step explanation:
We can split this into 20 triangles, each with an angle sum of 180 degrees.
So 180(20) = 3600 degrees.
Answer:
7
Step-by-step explanation:
In similar triangles, corresponding elements are proportional. Then we get,
(2x + 1)/(x-1) = 10/4
4(2x +1) = 10(x-1)
8x + 4 = 10x - 10
8x = 10x - 14
2x = 14
x = 7
