Answer:
38.5°
Step-by-step explanation:
A triangle solver can give an answer easily. The angle is 38.5°.
__
The law of cosines can be written to solve for an unknown angle C opposite side 'c' and flanked by sides 'a' and 'b'.
C = arccos((a² +b² -c²)/(2ab))
Here, we have a=35, b=48, c=30, so the angle is ...
C = arccos((35² +48² -30²)/(2·35·48)) = arccos(2629/3360) ≈ 38.515°
The angle the cable makes with the pole is about 38.5°.

Answer:
False
Step-by-step explanation:
If the angles are congruent then they have the same shape but the sides could be of different length. The 2 triangles are SIMILAR but not necessarily congruent.
Given line ax+by=c and point (h, k), the perpendicular line through (h, k) can be written as
b(x-h) -a(y-k) = 0
In order for this to be in standard form, it must be rearranged somewhat, and any common factors removed.
We can start with
20(x-8) -5(y-3) = 0
4x -32 -y +3 = 0
4x -y = 29
The standard-form equation of the desired line through (8, 3) is
4x -y = 29
