Answer:
E. 36
Step-by-step explanation:
You have to do a² + b² = c²
Plug in
15² + b² = 39²
225 + b² = 1521 (subtract 225 on both sides)
√b² = √1296 (square root on both sides)
b = 36

Answer:
D
Step-by-step explanation:
The exact value for the equation is true but I don't really think that's the question so anyways...
- 15.) The exact form for this equation is -13pi/3 and the decimal form -13.613...
- 16.) The exact form for this equation is 23pi/4 and the decimal form 18/064...
- 17.) The exact form is -7pi/2 as the decimal is -10.995...
- 18.) The exact is -29pi/6 and the decimal is -15.184...
Answer:
Parallelogram, I think
Step-by-step explanation:
I thought it was a rectangle because there were 2 sets of parallel sides with one set being a greater value than the other. What threw me off was the 45 degree angle. A rectangle's 4 angles are all 90 degrees. The only quadrilateral I knew that had 2 sets of parallel sides, has one side length greater than the other and did NOT have all 90 degree angles was the parallelogram.
hope this helps!
Answer:
Yes, it is 90 degrees
