Refer to the attached image.
Given:
and measure of exterior angle at C =
.
We have to determine the measure of angle B and angle BCA.
By applying exterior angle property of the triangle which states:
"An exterior angle of a triangle is equal to the sum of the opposite interior angles".
So, exterior angle C = 


Now, applying angle sum property in triangle ABC which states:
"The sum of all the angles of a triangle is 180 degrees".





Therefore, the measure of
and
.
Answer:
134.73
Step-by-step explanation:
Solving for m:
243 = m + 108.27
243 - 108.27 = m + 108.27 - 108.27
134.73 = m
Answer:
Should be 4/7
Hope it helps have a good day!
Answer: B data gathering
Step-by-step explanation:
all of those examples are examples of gathering data
The answer is 9 because its an odd number, not the sides of a triangle, can be divided be 3, and is a single digit number.
