To get angle Y, you have to do 90 - 27 to get the other angle in the triangle and you get 63. Then you do 180 - (63+51) which is 66.
Angle Y = 66
Answer:

Step-by-step explanation:
Given

Required
Write the variables and constants on different sides

Add 2x to both sides


Add 5 to both sides



Hence, the equation is

Solving further [divide both sides by 5]

Answer:
Step-by-step explanation:
Yes!
B. Both pairs of opposite angles are congruent.
A. Not A. The sides are not marked the angles are.
C. Not C. That would make a parallelogram. One of the conditions (sides) is not given.
D. Not D. Not given. It would make a parallelogram if that was what was given, but it is not.
E. Not E. Not given.
Essentially, the rule goes as so: odd + odd = even, even + even = even.
Although that may not be the answer you're looking for, it is a math rule that is never debunked and essentially the premises for why you get an even sum practically always depending on the numbers.
Hope this helps!
