The answer is 45! A triangle measures 180 in total so add all those three angles to get 180.
Answer:I think its not similar
Step-by-step explanation:
they dnot look the same
Subtract .018 from 9 to get the answer
9 - .018 = 8.982
Subtract the two equation from each other
-3x-7y=-66
-10x-7y=-24
--------------------
7x =-42
x=-6
by substituting in equation 1
(-3)(-6)-7y=-66
18-7y=-66
-7y=-84
y=12
so to check we substitute in the first equation
(-3*-6)-(7*12)=-66
18-84=-66
-66=-66
we check the second equations
-10(-6)-7(12)=-24
60-84=-24
-24=-24
