Answer:
He stepped back 59.71 feet.
Step-by-step explanation:
Start by making 2 triangles. One has 68 degrees as the acute angle at the base of the triangle and the other has 41 degrees as the acute angle at the base of the triangle. The side opposite of said angle on both triangles will be 80, the height of the tree. You're solving for the bottom (horizontal) side for both triangles.
For the triangle with an acute base angle of 68, the formula to solve for the horizontal side is tan(68) = 80/x.
Get x by itself to get 80/tan(68) = x
x = 32.32.
For the next triangle, the equation is the same but the angle is changed to 41.
tan(41) = 80/x
80/tan(41) = x
x = 92.03
Finally, subtract the smaller distance from the larger:
92.03 - 32.32 = 59.71 steps.
Answer:
hope this is right
Step-by-step explanation:
The majority of 65 degrees and up has more days than the others. But, That could change because we do not know how many day of the 12 year were 0- 32, 33 - 45, 46 - 64, and 65 degrees and up.
Answer:
you are correct
Step-by-step explanation:
Answer:
2a - 1
Step-by-step explanation:
I can only simplify
-3a + 2 + 5a - 3
2a + 2 - 3
2a - 1
