Answer:
4√5
Step-by-step explanation:
Answer:
18
Step-by-step explanation:
Because angle A and C are equal, it is an isoceles traingle.
This means that side BA is equal to side BC.
Thus, you can set 6x equal to 3x + 9.
Solving that gives you x = 3.
6(3) = 18 3(3) +9 = 18
Answer:
This is a single a step problem. When you subtract a positive you can flip the signs.
13) 180 degrees = 130 degrees + 3x + 2x
180 degrees = 130 degrees + 5x
subtract 130 from both sides to isolate the 5x
50 degrees = 5x
divide both sides by 5 to isolate the x
10 degrees = x
3(10) = 30 degrees
A = 30 degrees
Marie= X
andre= 3X
Jane=6X
840= X + 3X + 6X
840= 10x
Marie=84
andre=252
Jane=504
