Answer:
19. It only makes sense if cumm
20. Its a little harder to do this one, because cumm
21. cumm
Step-by-step explanation:
cumm
Note that when the two angles are combined, they form 90°
Solve for x.
5x + 15 + 20 = 90
Simplify. Combine like terms
5x + 35 = 90
Note the equal sign. What you do to one side, you do to the other. Do the opposite of PEMDAS.
Subtract 35 from both sides
5x + 35 (-35) = 90 (-35)
5x = 55
Divide 5 from both sides
5x/5 = 55/5
x = 55/5
x = 11
c. 11 is your answer

Answer:
C (The lower left one)
Step-by-step explanation:
I saw that the vertex was equal to (-1,1) and that is the only answer that makes sense
Answer and Step-by-step explanation:
The sides we have are 7, , and .
The square root of 80 is less than 9 but greater than 8 (because is 64, is 81, and 80 is in between those two values), and the square root of 31 is definitely less than the square root of 80.
So, is the longest side.
1) The square of is:
2) The sum of the squares of the two shorter sides is:
3) Since the square of the longest side is equal to the sum of the squares of the two shorter sides, by the Pythagorean Theorem, the triangle is a right triangles.
