⚠️ PLEASE HELP ⚠️ Find the measure of the red arc or angle

1 answer:

3 0

Answer: 51

Explanation: Angle EHF and angle EGF have the same according arcs (Arc EF).
Because angle EGF is an inscribed angle, you’ll double it to find arc EF (102). Then you’ll divide it by 2 = 51.
51 = EHF

The area of a trapezium is 800 cm2

svlad2 [7]

Answer:

The distance between the parallel sides is 20cm.

Step-by-step explanation:

Area of a trapezoid:

$A=\frac{a+b}{2}\times h$

where a and b are the 2 bases, and h is the height. The value we're trying to find here is the height.

3 of the 4 variables in this equation are already given:

A = 800

a = 48

b = 32

Just plug those in and solve for h:

$\rightarrow 800=\frac{48+32}{2}\times h\\\rightarrow 800=\frac{80}{2}\times h\\\rightarrow 800=40\times h\\\rightarrow 800\div40=h\\\rightarrow h=20$
