Answer:
1) yes 2) no 3) yes
Step-by-step explanation:
The lengths of the two shorter sides must be greater than the length of the longest side.
1) 8 + 9 > 10 yes
2) 1 + 1 = 2 no
3) 6 + 8 > 9 yes
In this problem you use cosine because you know the hypotenuse and you want to know the adjacent side of the triangle. So in your calculator you would input cos(52). Then you would multiply that answer with the hypotenuse side. So your equation would be this: cos(52) x 13

Step-by-step explanation:
They're still corresponding angles... have you read any of these explanations?...
x-17= 23
move -17 to the other side
sign changes from -17 to +17
x-17+17= 23+17
x= 23+17
Answer:
x= 40
