Need help on this quiz

1. They are supplementary angles

2. m<4 is 100 by vertical angles theorem

3.  m<5 is 100 since parallel lines form congruent angles

4. Alternate exterior angles are equal making the <b 38°

5. <9 and <10 are equal since they are corresponding angles and corresponding angles formed from parallels are equal. Complementary angles are those which add to 90°. Because they are complemenatary angles, their sum is 90 making each of them 45°

<9=45

6. IN a right triangle we know that one of the measures is 90° and sicne we know the other we can find the missing angle (third angle)

THe interior angles of any triangle add up to 180 and therefore 90+25+x=180

115+x=180

65=x

the answer is 4.8 units on e2020.

i would say c is the best answer, hope it's right!

good luck! =)
