To do this problem, you gotta cross-multiply. SO,
multiplied by
12 times 14 = 168
21 times 3 = 63
Then the final answer is
Answer:
x =20
Step-by-step explanation:
As a line is 180 degrees
So 7x + 40 would be 180, which would lead us with the equation:
7x+40=180
=7x =140 (minus both sides by 40)
=x =20 (divide both sides by 7)
Answer:
x = 30
since 3x = 90 degrees, then x = 90/3 = 30
