Answer:
angle made by the ladder with the ground is 59°.
Step-by-step explanation:
Ladder AC is placed 30 inches from a wall
It touches the wall as a height of 50 meters from the ground.
We have to find ∠C.
From the right angle triangle ABC.
Tan C =
Tan C =
C =
= 59°
Therefore, angle made by the ladder with the ground is 59°.

answer is 7
Step-by-step explanation:
We are given a piecewise function which has a split at x=0
f(x) =
To find the limit, we have to find here left hand limit and right hand limit separately.
Here left hand limit for x tending to 0 is
limit of as x tends to 0
= 7-0 = 7
Right limit = limit of 10x+7 as x tends to 0
=10(0)+7 = 7
Since right hand limit = left hand limit we have
there exists a limit for x=0 and the limit is 7
