Answer:
Answer:
h = \frac{2A}{b}
Step-by-step explanation:
Given
A = \frac{1}{2} bh
Multiply both sides by 2 to clear the fraction
2A = bh ( isolate h by dividing both sides by b )
h = \frac{2A}{b}
Answer:
A) 
Step-by-step explanation:
Area of a trapezoid is 
Its also 40°30' because the median is also a bisector in isosceles triangle
11 is 110 for x and y
12 is 90 degrees for x and y
13 is also 90 degrees for x and y
F+g(x) = f(x) + g(x) = 3x-1 + x+2 = 4x+1
