Answer:
y = 27°
Step-by-step explanation:
3y + 53 = 7y - 55
53 + 55 = 7y - 3y
4y = 108
y = 108 : 4
y = 27°
3(27) + 53 = 81 + 53 = 134°
X=23
I say this because you can see that the scale factor is 3 due to just visually scaling both the long and short leg from the original triangle to the dilated triangle. Dividing 39 by 3 is 13, and doing it in reverse. Adding 10 would equal 23, the initial value. So that'd be the missing value.
A prime number is a number that can have factors that is only 1 and itself. A composite number is a number that can have many differnt factors.
Answer:
The question confused me a bit because of the different numbers.
The answer would be
w(2 * 18), which would be the same as choice a if the numbers weren't different.
Step-by-step explanation:
Take 10x +55x first making 66x
then you'll have 66x^2 +25 for you simplified answer
