(7,3)
Step-by-step explanation:
X= -2+3y
....
-2+3y-3y=-2
-2+3y+3y=16
.......
6y=18
...
y=3
x=7
Given: ∠A is a straight angle. ∠B is a straight angle.
We need to Prove: ∠A≅∠B.
We know straight angles are of measure 180°.
So, ∠A and <B both would be of 180°.
It is given that ∠A and ∠B are straight angles. This means that <u>both angles are of 180°</u> because of the <u>the definition of straight angles</u>. Using <u>the definition of equality</u>, m∠A=m∠B . Finally, ∠A≅∠B by <u>definition of congruent. </u>
We have some couples of angles that are equal
