Answer:
118
Step-by-step explanation:
AD = BD
5x - 11 = 3x + 17
Move the constants to the one side
5x - 11 = 3x + 17
+ 11 + 11
5x = 3x + 28
Move the constants to the other side
5x = 3x + 28
- 3x -3x
2x = 28
Divide both sides by 2
2x/2 = 28/2
x = 14
Let's move back to the original equations
Substitute x with 14
5(14) - 11
3(14) + 17
Use Order of Operations
5(14) - 11 = 59
3(14) + 17 = 59
Add up both answers
59 + 59 = 118
Answer:
a = 30 degrees; b = 60 degrees; and c = 105 degrees.
Step-by-step explanation:
Angle a and the 30 degree angle are vertical angles and thus are equal.
Since the interior angles of a triangle always add up to 180 degrees, 30 + b + 90 degrees = 180 degrees, so that b must be 60 degrees.
Angle c and the 75 degree angle are straight angles, and so their sum must be 180 degrees. Thus, c = 105 degrees.
<u>Solution</u>:
It is given that length of a rectangular room is 6.9 m and its width is 9.6 m.
So We have ;
- Length of Rectangular room = 6.9 m
- Length of Rectangular room = 6.9 m Width of Rectangular room = 9.6 m
<u>So We have to find the area of the room.</u>
We know :
<h3>Area of Rectangle = Length times Width </h3>
<u>Area of Rectangular room = Length of Rectangular room × Width of Rectangular room </u>
Area of Rectangular room = 6.9 m × 9.6 m
Area of Rectangular room = 6.9 m × 9.6 m Area of Rectangular room = 66.24 m²
Therefore, Required area of the room is 66.24 m².
Answer: the slope to these points would be 0
