steps
area of trapizium is a+b/2 * h.
we have a=14, h=15, area=330 and we need to find b
so, 14+b/2 * 15=330
we divide 15 on both sides so 14+b/2=22
we multiply 2 on both sides so 14+b=44
b=44-14
b=30
10x=15+11x if this isnt correct please edit your question
0.2+z= 0.2y +1z
That only one but I believe in you
You really smart own it
Answer:
<Ber=<kem(vertically opposite angle)
9x-17=3x+31
9x-3x=31+17
6x=48
x=48/6=8
<kem=3×8+31=55°is answer
First, we get the length of the runway in which the pilot had seen a 45° by using the trigonometric formula of tangent.
tan 45° = 1,500 / x
The value of x from the equation is 1500 ft.
We do the same for the 42°
tan 42° = 1,500 / y
The value of y is equal to 1665.92 ft. To determine the length of the runway, we subtract the lengths calculated and this will give us an answer of 165.92 ft.
