Answer:
243.84
Step-by-step explanation:
We change feet to inches, and inches to cm.
1 ft = 12 in.
1 in. = 2.54 cm
8 ft * (12 in.)/(1 ft) * (2.54 cm)/(1 in.) = 243.84 cm
8 ft = 243.84 cm
5x+3x=90+30
8x=120
(1/8) (8x) = (1/8) (120)
x=15
m<JAH= 3(15)=45
m<HAG= 5(15)=75
and the first one is
<KAE and <EAF are adjacent angles whose measurements are equal to
<KAF; <KAF and <JAG are vertical angles and are of equal measurement.
Answer:
The answer is \frac{2A}{h} -b_2=b_1
Step-by-step explanation:
Given that the area of a trapezoid is ;
A=1/2 (b₁+b₂)h
When the equation is solved for b₁ it will be;
A=1/2 (b₁+b₂)h
This can be written as;
A=h/2 (b₁+b₂)
Multiply both sides by 2/h
2A/h = b₁+b₂
Make b₁ subject of the formula
2A/h - b₂ = b₁
An=Asub1+d(n-1)
Asub5= -5+½(4)
=-5+7
=2
