Answer:
35
Step-by-step explanation:
You have to add up the two angles that it gives you which are 90 and 55. That'll equal 145. Since all the angles added together in a triangle are supposed to equal 180, you subtract 145 from 180 to get your answer of 35.
The linear pair of angles add up to 180 degrees (they are supplementary). The linear pair of angles are adjacent and they form a straight angle (aka straight line)
4x+x = 180
5x = 180
5x/5 = 180/5 ... divide both sides by 5
x = 36
Answer: 36
First, you want to insert 15 for n:
100 + 4(15)
Next, multiply 15 and 4:
100 + 60
Finally, add 100 and 60 together:
160
You should get 160.
Hopefully that helped! :)
