Answer:
The whole triangle is 180° , and means + in math
15-x + 2x= 180
-x+2x=180-15
-x+2x=165
2x=165
2x/2=165+/2
=82.5
Answer:
-10
Step-by-step explanation:
The constant is the part of the algebraic function or expression that does not change. In this case, as x changes, the constant -10 does not. Thus, -10 is the constant.
12(7x)^1/5
This is simplification into index form, the index itself is the 5th root of 7x if you just wanted to state what it is
