Answer:
∠a = 10°
Step-by-step explanation:
The measure of ∠a = x
The measure of ∠b = 4x-30
It is also mentioned that the measure a and measure b are vertical angles. We need to find the value of a.
For vertically opposite angles,
∠a = ∠b
x = 4x-30
or
4x-30=x
Taking like terms together,
4x-x= 30
3x = 30
x = 10
So, the meausre of ∠a is equal to 10°.
Answer: A Hexagon
Step-by-step explanation:
To solve this problem, we must remember that division is the inverse operation of multiplication. This means to undo any multiplication problem, we can divide.
Because 8 * -2 = -16, if we divide the product by the two factors, we can reveal this unique relationship, as shown below:
-16/-2 = 8
-16/8 = -2
Therefore, the two division problems above are your answer.
Hope this helps!
Answer:
19
Step-by-step explanation:
4×4= 16+12= 28
2×3= 6+3= 9
