35 x 0.2
= 7
Answer:
-5/2
Step-by-step explanation:
Use slope formula:
Given 2 points (x1, y1) and (x2, y2) Slope is
y2-y1/x2-x1
The x intercept is 2, the point would be (2,0)
The y intercept is 5, the point would be (0,5)
So you can do (5-0)/(0-2) which is 5/-2 which then would be -5/2
CD = x
BC = y
AB = 85
BD = BC+CD = y+x
tan(angle) = opposite/adjacent
tan(28) = BC/AB
tan(28) = y/85
85*tan(28) = y
y = 85*tan(28)
y = 45.1953016912257
tan(angle) = opposite/adjacent
tan(31) = BD/AB
tan(31) = (y+x)/85
tan(31) = (45.1953016912257+x)/85
85*tan(31) = 45.1953016912257+x
51.0731526173427 = 45.1953016912257+x
51.0731526173427-45.1953016912257 = 45.1953016912257+x-45.1953016912257
5.877850926117 = x
x = 5.877850926117
So CD is roughly 5.877850926117 meters
This is the answer for both number 9 and number 11.
Good luck
