Answer:
D is 117
Step-by-step explanation:
Let the measure of angle C be x
The measure of D is 9 less than twice C
Mathematically that is 2x-9
If both are supplementary, they add up to be 180
Thus;
x + 2x - 9 = 180
3x = 180 + 9
x = 189/3
x = 63
Recall;
D = 2x-9= 2(63) -9 = 126 -9 = 117
Answer:
23 and 25
Step-by-step explanation:
x and x+2
x+3(x+2)=98
x+3x+6=98
4x=92
x=23
x+2=25
Answer:
The value of H is 28.
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(H-6)/(-7-(-5))
m=(H-6)/(-7+5)
-11=(H-6)/-2
-11(-2)=H-6
22=H-6
H=22+6
H=28
