Please help with math?

Could someone please help me

1. Find the measure of angle ABD if the measure of angle ABC=57, the measure of angle ABD is represented by 2x-1 and the measure of angle DBC is represented by 5x+2. Angle A B and C contain ray B D Angles A B D and D B C are adjacent

A) 7

B) 8

C) 15

D) 42

2. What is the measure of angle DBC if the measure of angle ABD is represented by 2x, the measure of angle DBC is represented by 5x and the measure of angle ABC is 91 degrees? Angle A B and C contain ray B D Angles A B D and D B C are adjacent

A)7

B) 13

C) 26

D) 65

3. Find the measure of angle ABD if the measure of angle DBC is 16 degrees and the measure of angle ABC is 89 degrees.Angle A B and C contain ray B D Angles A B D and D B C are adjacent

For the first one:

(2x -1) + (5x+2) = 57

7x +1 = 57

7x = 56

x=8

Angle ABD = 2x-1

2(8) -1 = 15

Answer:

C. 15

#2 Very similar

2x + 5x = 91

7x = 91

x = 13

Angle DBC = 5x

5(13) = 65

Answer:

D. 65

#3 Just subtract

89-16 = 73

Answer:

D. 73

#4.

B. a point

The line does not lie on the plane, so imagine a piece of paper with a pencil sticking through it. It intersects the paper at a single point.
