DOUBLE VALUE!!!
Angle A and Angle B are complementary.
If angle A is 70 degrees
and angle B is 4x
What is the value of x?
x = 5
-21 = -16y + 11
y= 2
10 = 1 - y
y = -9
23=x/3+26
x=-9
m+2=-7
Angle A and Angle B are vertical angles.
If Angle A is 105 degrees
Angle B is 7x
What is the value of x?
-2(x+8) = 10
x = -13
DOUBLE VALUE!
-3(r-7)=-24
r=15
5x - 1.50 = 13.50
x=3
p/6=9
p=54
Angle A is 70 degrees
Angle B is 6x + 20
Angles A and B are supplementary.
FIND X AND ANGLE B
x = 15
Angle A = 110 degrees
-3x + 4 - 5x + 7 = 99
x = -11
3/2m - 10 = -7
m = 2
1/2( 4x - 10) = 11
x = 8
y - 10 = -5
y=5
