Hi, I need some help on this question

Write an equation to determine the measures of both angles.
Determine the measures of both angles. Show your work.

∠1 =20x+21 and the measure of ∠2+30x - 29

A: Write an equation to determine the measures of both angles.
B: Determine the measures of both angles. Show your work.

A : 20x+21=30x-29

B : m<1 = 121   m<2 = 121

Step-by-step explanation:

Original equation

Add +29 to both sides

Subtract -20x

Divide by 10

Checking your work and doing substitution

20(5)+21

100+21

121

30(5)-29

150-29

121

18

step-by-step explanation:

draw the shape and you will see that f and k are actually at adjacent vertices (points of the hexagon that are neighboring).   so find the distance between (1,2) and (4,2).   that is easy since (1,2) and (4,2) is just a vertical distance to count, which is 3.   it is a regular polygon which means all sides are congruent.   you have 6 sides (hexa) so multiply 6 by 3 to receive 18.
