The bottom line is a straight line that is equal to 180 degrees.
The three angles above it all need to add together to equal 180.
One angle is given as 20, so the other two need to add together to equal 160 ( 180-20 = 160)
Those two angles form the angle ACE so the answer would be 160 degrees,
Answer 160 degrees.

Answer:
Step-by-step explanation:It sounds and looks to me as if you just need to find the missing number that goes between the second and last number.
To answer this question we will have to keep the following two points in mind:
#1. The <u>sum</u> of a number with another number means to <u>add </u>the given two numbers.
#2.<u> Twice</u> means to <u>multiply by 2.</u> In other words it means to double.
Therefore, "twice the sum" would mean to multiply the sum by 2.
Now, in our question we will have, "the sum of y and 9 would be: and twice this sum would be:
Thus, "twice the sum of y and 9" is:
For this equation, all we have to do is substitute 5 in for "n" as we want to find the 5th term in the sequence.
3(n-3)
3(5-3)
3(2)
6
The 5th term in the sequence is 6.
