Answer:

1) 103 degrees

2) 109 degrees

3) 65 degrees

Step-by-step explanation:

1) A line is 180 degrees, so 180 - 77 = 103 degrees. y = 103

2) All the angles in a triangle add up to 180 degrees, so 64 + 45 = 109. 180 - 109 = 135. x = 135

3) same as the last one, 68 + 47 = 115. 180 - 115 = 65. x = 65

Two vertical angles have measures (4x-21)° and (x+6)°. Find the measures of the angles
Arte-miy333 [17]

The measure of the two vertical angles is 15°

The two vertical angles have measures (4x-21)° and (x+6)°

Note that:

The measure of two vertical angles are equal

Therefore, equate  (4x-21)° and (x+6)° and solve for x

(4x-21)° =  (x+6)°

4x  -  21   =  x   +  6

Collect like terms

4x  -  x   =   6  +  21

3x    =  27

x   =  27/3

x    =   9

Substitute x = 9 into 4x - 21

4x - 21 = 4(9)  -  21

4x  -  21  = 15°

Substitute x = 9  into x + 6

x  +  6  =  9  +  6

x  +  6  =  15°
