Answer:
61 degrees
Step-by-step explanation:
a triangle measures 180 degrees
so your going to add 87 and 32 which gives us 119
since a triangle measures 180 degrees u you are going to subtract 119 from 180 which gives us 61 degrees
9-24=4(3)
-15=4×3
-15=12
27/40
127
We started at 7
We keep going up 3
multiply
Now add at the 40th term
