Answer:
x = 58/3
Step-by-step explanation:
We can use cross products to solve this problem
6 7
---------- = -----------
14 x-3
6 * (x-3) = 7 * 14
Divide each side by 6
6 /6* (x-3) = 7 * 14/6
x-3 = 98/6
Add 3 to each side
x-3+3 = 98/6 +3
x = 98/6 +18/6
x = 116/6
Divide the top and bottom by 2
x =58/3
Answer:
Area = 1/2 b x h
18 = 1/2 ((x) x 4x)
18 =1/2 4x^2
36 = 4x^2
36/4 = x^2
9 = x ^2
x = 3
Base = 3 m
Height = 4 x base = 4 x 3 = 12 m
Step-by-step explanation:
The 2 angles given are vertical angles, which mean they are the same.
So we have: 3x +1 = 64
Subtract 1 from each side:
3x = 63
Divide both sides by 3:
X = 63 / 3
X = 21
The answer is A.
