Answer:
See explanation below.
Step-by-step explanation:
He has to remember that b is the y-intercept and in this case it is 5 so he can automatically graph that point. Next, he has to recall that the number before the x is the slope and in this case it is -4 so he can use this to graph the line correctly.
Answer:
28°
Step-by-step explanation:
1. We can see that ∠GFH has two smaller angles within it: ∠1 and ∠2. Given that m∠GFH is 53° (the whole thing), and m∠2 is 25° (a part of it), we just have to subtract 25 from 53 to get the measure of ∠1.
Therefore, m∠1 = 28°.
To write the slope form quation
First; find the slope of
using the formula above for finding area of trapezoids
a= 20in.
b=29.2in.
h= height= 12.5in.
(a+b)=20+29.2=49.2in.
(a+b)h= (49.2)12.5= 49.2×12.5=615in.
1/2(a+b)h= 1/2 × 615 in.= 615/2= 307.5in.
therefore the area of the trapezoid is 307.5in.
Step-by-step explanation:
Pythagoras
c² = a² + b²
with c being the Hypotenuse (the side opposite of the 90 degree angle).
x² = 12² + 9² = 144 + 81 = 225
x = 15 ft
so, the first answer option is correct.
