Hey there,
Both

= 85 and

are 80°.
1.) First off, the reason why there would be 80° would be because by looking at this angel, this angel is a obtuse angel. And also, it is also close to being a (right angel). And a right angel is 90°. So this is a clue that it would be around there.
2.) The area of this figure would be 300°.So in order to find the other angel's, we would have plug in both <em>x =85 and also y=80.
</em>Hope this helps.

Answer:
11x-9
Step-by-step explanation:
5+2(5x-7)+x=5+10x-14+x
= 11x-9
Answer: X = 2
Step-by-step explanation: To find the value of "X" in this equation, we first need to subtract 3 from both sides.

19x³ + (14x + 4x³)=
You can assume that there is a 1 in front of the parentheses, so you can distribute the one to each term in the parentheses.
19x³ + 1(14x+4x³)=
19x³ + 14x + 4x³=
Then combine like terms to get 23x³ + 14x.
So 19x³ + 14x + 4x³= 23x³ + 14x
