Answer:
-26
Tip for solving related problems: use order of operations
the value of m is 24°
Step-by-step explanation:
m+7+2m+11=90° ( being complementary angle)
3m+18°= 90°
3m =90- 18°
3m = 72
m= 72/3
m=24°
Answer: They are parallel
Step-by-step explanation:
If two lines are parallel , then they must have the same slope and if two lines are perpendicular , the product of their slope must be -1.
To check this , we must calculate the slope of the two lines given.
Slope = 
from the first point
= 2
= 1
= 5
= -1
substituting the values
slope 1 = 1 - 2 / -3 - 5
slope1 = -1 / -8
slope 1 = 1/8
Using the same format to calculate the slope of the second line
= -2
= 0
= -1
= 15
slope 2 = 0 - (-2) / 15 - (-1)
slope 2 = 2/16
slope 2 = 1/8
Since slope 1 = slope 2 , this implies that the lines are parallel

Step 1) Check if the given triangle lengths form a right triangle
3^2 + 5^2 = 6^2
9 + 25 = 36
36 = 36
Step 2) Solve for the area of the triangle
Formula: A = 1/2 x base x height
A = 1/2 x 3 x 5
A = 1/2 x 15
A = 7.5 m^2
Step 3) Solve for the perimeter of the triangle
Formula: P = sum of all sides
P = 3 + 5 + 6
P = 14 m
Ravi needs to plant 7.5m^2 of grass and put up a fence that is 14m in total length.
Hope this helps!! :)
