Answer:
7) 49°
8) 77°
9) 87°
10) 135°
Step-by-step explanation:
7) The angles are between the parallel lines, so are "interior." They are on opposite sides of the transversal, so are "opposite interior" angles. Such angles are congruent, so ...
... ? ≅ 49°
8) The angles are adjacent interior angles, so are supplementary.
... ? + 103° = 180°
... ? = 77°
9) The angles are outside the parallel lines, so are "exterior." They are on opposite sides of the transversal, so are "opposite exterior" angles. Such angles are congruent.
... ? ≅ 87°
10) These are vertical angles, so are congruent. (The other parallel line is irrelevant and doesn't need to be there for this relationship to be true.)
... ? ≅ 135°
Answer:
angle y is 64⁰
Step-by-step explanation:
There are 2 ways to solve this.
first,
they are alternate angles
second,
you can solve by
180-64=116 (on a straight line)
180-116=64⁰
I'm not really good at explaining but hope this helps :)
The statement that is correct is E
90 degrees
cuz if you look closely it says isosceles RIGHT triangle
A right triangle has a measure of 90 degrees
