Answer:
x = 60°
Step-by-step explanation:
since, the triangles are complementary the sum of their measures will be 90°
now,
First we have to distribute the parentheses on the left side, 2*x is 2x and 2*-3 is -6, so now the equation is 4x+2x-6 = 8x+12
Then, we can add together the two x's on the left side,
so now we have 6x-6 = 8x+12 Subtract 12 from both sides and
you get 6x -18 = 8x Then you can subtract 6x from both the sides and get
-18 = 2x Now we can divide both sides by 2, and the final answer is -9 = x
Since they are not the same and the two sides aren't unequal, there is one solution(:
Hope this is helping you(:

Answer: c
could you help me on a question i have?
Answer:
x=-7
Step-by-step explanation:
-(x-13)=10(x+9)
distribute the negative on the left side and the 10 on the right side
-x+13=10x+90
add x on both sides
13=11x+90
subtract 90 on both sides
-77=11x
divide 11 on both sides
-7=x
x=-7
