Answer:
35
Explanation:
Because of the box in the graph, you can tell that this is a 90-degree angle
2x means the next angle will be twice of the answer choice number
because the end product must be 70 the answer must be 35
35 x 2 = 70
B. 45
we know the sum of both angles is 90 because of the small sqaure in the corner.
90 = 2x+20
70 = 2x
45 = x
