Question 1:This is a 45-45-90 right triangle. If the leg length is 

, then the hypotenuse length will be 

.
The leg length of this 45-45-90 right triangle is 8. Multiply that with the square root of 2. You get 

. Thus, the last choice is your answer.
Question 2:This triangle can be identified as a 30-60-90 right triangle.
Let's say the smallest leg as a length of 

.
Then, the longer leg will have a length of 

.
Also, the hypotenuse will have a length of 

This triangle follows this format, making it a 30-60-90 right triangle. Thus, the angles are 30, 60, and 90.
Hope this helps! :)
