Answer:
Hey can you tell me what I am supposed to be looking for?
Step-by-step explanation:
Answer:
120 m
Step-by-step explanation:
Let the length of the pole be a and the shadow be b at 58° and b+90 at 36°.
<u>Then, as the pole and its shadow form a right triangle, we have:</u>
<u>As,</u>
- tan (58°) ≈ 1.6
- tan (36°) ≈ 0.727
<u>The equations change to:</u>
<u>Comparing the two equations:</u>
- 1.6b = 0.727b + 0.727*90
- 1.6b - 0.727b = 65.43
- 0.873b = 65.43
- b = 65.43/0.873
- b ≈ 75
<u>Then </u>
- a = 1.6b = 1.6*75 = 120 m
Answer:
y = -2x + 2
Step-by-step explanation:
8 + 4/ -6
= -2
y = -2x + b
8 = -2(-3) + b
8 = 6 + b
2 = b
check work
-4 = -2(3) + 2
-4 = -6 + 2
-4 = -4
it is correct
