Answer:
Step-by-step explanation:
1. 6f+45+15=180
6f=180-45-15
6f=130
f=130/6=65/6=21.66666666666666....
2. d=6f=130/6=65/6=21.66666666666666....
(They are vertical angles, opposite angles)
Set them equal to each other because they are parallel
3x+7=5x-17
Subtract 3x from both sides
7=2x-17
Add 17 on both sides
24=2x
Divide by 2 on both sides
12=x
Answer:
x=-35
Step-by-step explanation:
136+12x=-4(1-2x)
136+12x=-4+8x
+4 +4
140+12x-12x=8x-12x
140/-4=-4x/-4
x= -35
Answer:
100
Step-by-step explanation:
cosB = 36/60 = 3/5
cosB = 60/x = 3/5 -> x = 100
