Step-by-step explanation:
1.
The GCF of all the term of the above polynomial is
, hence we take it outside and form a bracket
The polynomial within the bracket can not be factorized further hence this is our final answer. Option (B) is the right answer

Answer: x = 3
Explanation:
If the two triangle are congruent then all of their sides are also congruent.
4x + 1 = 13
4x = 13 - 1
4x = 12
x = 12/4 = 3
Answer:

Step-by-step explanation:
Given that,
The height of a cell tower, P = 70 m
The tower casts a shadow of 45 meters on the ground.
We need to find the angle of elevation of the shadow to the top of the cell tower. We can use trigonometry to find it.

Put all the values,

Hence, the angle of elevation is equal to
.
