PLEASE HELP ME QUICKK

Answer 1

75 degrees

All triangle angles will always add up to 180 degrees, so if A is 64 and B is 40, add those for 105. 180 minus 105 is 75. Therefore, C is 75.

Answer 2

Answers:

1st page

Angle A=65 degrees

Angle B=40 degrees

Angle C = 75

65+40+x=180 degrees

105+x=180degrees

x=180-105

x=75 degrees

2nd page

Angle A=59 degrees

Angle B=48 degrees

Angle C=73 degrees

To find x

x+x-11+73=180 degrees

2x+62=180 degrees

2x=180-62

2x=118

(equate both sides)

x=59 degrees

3rd page

Angle A=35 degrees

Angle B=100 degrees

Angle C=45 degrees

To find x

x+35+45=180 degrees

80+x=180degrees

x=180-80

x=100 degrees

4th page

Angle A=45 degrees

Angle B=110 degrees

Angle C=25 degrees

To find X

x+x+65+25=180 degrees

2x+90=180

2x=180-90

2x=90

(equate both sides)

x=45 degrees

5th page

Angle A=48 degrees

Angle B= 88 degrees

Angle C= 44 degrees

To find X

48+x+x-44=180 degrees

4+2x=180 degrees

2x=180-4

2x=176

(equate both sides)

x= 88 degrees
