20a. 143 deg

20b. 37 deg

20c. corresponding angles, congruent

20 d. same-side interior angles, supplementary

Step-by-step explanation:

20a.

m<7 = 34

m<5 + m<7 = 180       (linear pair)

m<5 = 180 - 37 = 143

m<4 = m<5 = 143      (alt int angles)

20b.

m<2 = m<7 = 37     (alt ext angles)

20c. corresponding angles, congruent

20d. same-side interior angles, supplementary

(a)

∠7 = 37° = ∠6 ( vertical angles )

∠4 = 180° - 37° = 143° ( 4 and 6 are supplementary interior angles )

(b)

∠2 = 37° (2 and 4 form a straight angle )

(c)

∠4 and ∠8 are corresponding congruent angles

(d)

∠3 and ∠5 are supplementary interior angles

answer4 to the second power is 16

and 4 to the third power is 64,

false

step-by-step explanation:

false : it can not go to 9 the highest that part can go is 7

here is your proof
