180°=2x+10x+12
180=12x+12
168=12x
x=14
angle J=2x
J=2(14)
J=24
angle K=10x+12
K=10(14)+12
K=140+12
K=152
therefore, answer is C.
Answer:
x = 15
Step-by-step explanation:
Since the triangles are similar we can find x using similarity ratio
14/8 = (x+6)/(x-3) simplify first expression
7/4 = (x+6)/(x-3) cross multiply expressions
7×(x-3) = 4×(x+6)
7x-21 = 4x + 24 add like terms
3x = 45
x = 15
Answer:
B
Step-by-step explanation:
2x+8=9
you want to isolate the variable so you subract 8 from both sides
2x=1
now you want x by itself so you divide by 2 on both sides
x=1/2 or x=0.5
Hope this helped :)
