Question

100 Points!!! I need these three solved and I need them solved FAST. pls help me.

Answer 1

Answer:

7)   40

8)   23

9)   63

Step-by-step explanation:

180 degrees in a triangle.  Add the 2 degrees they give you, and then subtract that from 180 to find the missing angle.

82 + 58 = 140    180 - 140 = 40

115 + 42 = 157    180 - 157 = 23

27 + 90 = 117     180 - 117 = 63

Hope this helps.

Answer 2

Answer:

7=40, 8=23, and 9=63

Step-by-step explanation:

The key info to solve is that in a triangle there are 180 degrees

7) we add 82 and 58 and then subtract the total from 180 to find x

=82 + 58 = 140, and 180 - 140 = 40, so 40=x

We do the same for the rest

115 + 42 = 157, and 180 - 157 = 23, so 23=x

Wait whats that square in the triangle? It represents 90 degrees, a right angle!

so, 27 + 90(right angle) = 117, and 180 - 117 = 63, so 63=x
