Kate had a test and one of the questions were 8 dived by 2 +( 6+7)+3. She answered by saying it was 13.625 . When the teacher graded it she marked it wrong then handed it to Kate saw that it was wrong. She wondered why so she asked the teacher and said why she got it wrong and explained that the parenthesis are show that you need to solve the number in it first before you do anything else. Then Kate tried to solve it again and got 20.

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:

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
