Answer:
62.2° (or 1.1 rad)
Step-by-step explanation:
Let’s call the three points A Allen’s house, B Bob’s house, T the traffic light and α “angle of depression”.
Since we have a right triangle BTA, let’s first find out the angle ∡BTA based on its opposite side AB = 7 km and the hyponenuse TA = 15 km.
∡BTA = arcsin(AB/TA) ≈ arcsin(0.4667) ≈ 0.4855 rad or 27.82°
Now since the text says the connecting line TA “is vertical to the road”, α is the rest of the right angle when ∡BTA subtracted.
α ≈ 90° - 27.82° = 62.18°
or α ≈ 0.5 π rad - 0.4855 rad ≈ 1.09 rad
See above for properly rounded values.
There is one restriction: The number whose square root is needed can not be negative
the scale is x4
because 10x4=40
11x4=44
18x4=72
you multiply by 4 on all of them
Answer:(X x 4)=
Step-by-step explanation:
Basically u times how many tickets u need times how much it cost
Example( 1ticket X 4dollars) =4 dollars
The answer is c. 48 because angle 3 and 132 equals 180 because they are supplementary angles. So... 180 - 132 = 48 <—- angle 3
