Answer:
Step-by-step explanation:
-7 -x - 3 = 12
-x - 10 = 12
-x = 22
x = -22
1) perpendicular
2) parallel
3)perpendicular
First 4 multiple by 6 then add 1
6*4=24
24+1=25
Answer is: 25/4
Answer:
360°
Step-by-step explanation:
According to the properties of parallel lines, the following deductions can be made:
<a and <c are exterior angles of same side, therefore they are supplementary.
Thus,
m<a + m<c = 180°
<b and <d, are alternate interior angles, therefore, they are supplementary.
Thus, m<b + m<d = 180°.
The total numbers of degrees of a, b, c, d will all sum up to give 360°.
It’s 12h-14 because -6 and -8 combine to be -14 and 5h and 7h equal 12h
