Answer:
80 feet.
Step-by-step explanation:
Given:
The length of a rectangular garden is 10 yards and its width is 10 feet.
To find:
Perimeter of the garden in feet ?
Solution:
Length = 10 yards
1 yard = 3 feet
10 yards = 3 
10 = 30 feet
Breadth = 10 feet
Now, as we know:
Hence, the perimeter of the garden is 80 feet.
Your answer would be: m = 63/4 in fraction form and m = 15.75 in decimal form.
Hope this helps and happy holidays!!
Answer:
∠ B = 45°
Step-by-step explanation:
∠ A and ∠ Bare alternate exterior angles and are congruent , then
5x - 15 = 2x + 21 ( subtract 2x from both sides )
3x - 15 = 21 ( add 15 to both sides )
3x = 36 ( divide both sides by 3 )
x = 12
Then
∠ B = 2x + 21 = 2(12) + 21 = 24 + 21 = 45°
