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
Answer:
A: (1,1)
B: (6,6)
Step-by-step explanation:
Given:
A chef prepares apples for a fruit salad. She cuts each apple into 6 slices.
The following patterns can be made:
Pattern A: start with 1 apple and increase by 1 apple.
Pattern B: start with 6 slices and increase by 6 slices.
To find : ordered pairs which represent the number of apples from Pattern A and the number of apple slices from Pattern B
Solution :
Pattern A:
If a chef starts with one apple then increase by 1 apple then ordered pair which represent this pattern is (1,1)
Pattern B :
If a chef starts start with 6 slices and increase by 6 slices then ordered pair which represent this pattern is (6,6)
Does the equation represent a direct variation?
