What is the length of AB?
2 answers:
Answer: The correct option is (C) 6.
Step-by-step explanation: We are given a triangle ABC in the figure, in which
We are given to find the length of side AB.
In ΔABC, we have
We know that in a triangle,
if two angles have equal measures, then the sides opposite to them are equal in length.
So, we must have
Therefore, the length of AB will be
Thus, the length of side AB is 6 units.
Option (C) is CORRECT.

Alright, lets get started.
If the polygon measures 45 degree exterior angle and we are asked to find number of sides, there is a formula for that.
= value of exterior angle
Where n is number of sides of ploygon
Multiplying n into both sides
Now divide 45 in both sides
n = 8
Means number of sides of polygon is 8, hence its Octagon. Answer
Now we have given 45 exterior angle hence interior angle would be
180 - 45 = 135°
So, sum of all interior angles would be = number of sides * interior angle
sum of all interior angles would be =
Hence sum of all interior angles would be 1080°. Answer
Hope it will help :)
