All angles in a triangle add up to 180 degrees. So, if you are missing an angle, add up the degrees of the angles present and subtract that from 180. That will be the value of the missing angle in degrees.
Answer:
18 ft
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
144 = 8w
Divide each side by 8
144/8 =w
18 =w
X=96
first add the one to the 15 then multiply it by 6 and you get 96
