Answer:
1. (B) 73
2. r = 15
Step-by-step explanation:
1. The sum of angles in a triangle is 180°.
62° +45° +k° = 180
k = 180 -107
k = 73
__
2. The sum of exterior angles of any polygon is 360°.
4r° +7r° +5r° +8r° = 360°
24r = 360 . . . . . . . . . . . . . collect terms, divide by °
r = 360/24 . . . . . divide by 24
r = 15

The slop of the line that is represented by the equation -5x + 2y = 10 is
Answer:
Step-by-step explanation:
The slope intercept form is 
.
The "
" is the slope; which in this case is -3. So 
.
The "
" is the y-intercept, which is this case is the -8 because it is the 2nd number in the coordinate point.
This is why the answer is .
X= 103
180 - 65 = 115
X + 12 = 115
X = 115 - 12 = 103
