Answer:
-3y
Step-by-step explanation:
-15(y2)4 ÷5y3y4
Rewrite the division as a fraction
<u>-15(y2)4</u>
5y3y4
Multiply y3 by y4 by adding the exponents
<u>-5(y2)4</u>
5y7
Cancel the common factor of -15 and 5
<u>-3(y2)4</u>
y7
Multiply the exponents in (y2)4
<u>-3y8</u>
y7
Cancel the common factor of y8 and y7
Factor y7 out of -3y8
<u>y7(-3y)</u>
y7
Multiply by 1
<u>y7(-3y)</u>
y7 × 1
Cancel the common factor which is y7 and y7
Rewrite the expression
<u>-3y</u>
1
Divide -3y by 1
-3y
Answer:
ABC = 87°
Step-by-step explanation:

3x = 165
x = 55
ABC = 55 + 32 = 87
