Answer:
m = 7
Step-by-step explanation:
The 3 given angles lie on a straight line, thus sum to 180° , then
8m - 4 + 90 + 5m + 3 = 180, that is
13m + 89 = 180 ( subtract 89 from both sides )
13m = 91 ( divide both sides by 13 )
m = 7
Answer:
The midpoint of the horizontal line segment (-6, 3) (10, 3) is (2, 3)
Step-by-step explanation:
The midpoint formula: (x1+x2)/2 , (y1+y2)/2
(-6+10)/2 , (3+3)/2
4/2 , 6/2
2, 3
Answer:
Yes, it is a right triangle.
Step-by-step explanation:
A right triangle follows the rules of 3,4,5 side lengths, in which 5 is the hypotenuse, 3 is the shortest side, and 4 is the opposite side.
Plug it into the equation. The equation you will use is:
(shortest side)² + (longer side)² = (hypotenuse)²
(9)² + (40)² = (41)²
Simplify. First, solve the power:
(81) + (1600) = (1681)
Simplify. Combine like terms:
(81 + 1600) = 1681
1681 = 1681 (True)
Yes, these sides can be used to make a right triangle.
