Answer:
θC = π/4
Step-by-step explanation:
To find the desired angle, subtract multiplies of 2π until the angle is in the desired range.
9π/4 -2π = (9-8)π/4 = π/4
The angle θC = π/4 is coterminal with θ = 9π/4.
Answer:
x = 52, y = 137 degrees.
Step-by-step explanation:
x = 180 - 90 - 38
x = 52 degrees (as there is 180 degrees in a triangle).
As they are the same side inner angles between 2 parallel lines:
x + (y - 9) = 180
52 + y - 9 = 180
y = 180 - 52 + 9
y = 137 degrees.
Let's assume
length of rectangle is L
width of rectangle is W
the width of a rectangle is 3 meters more than one-fourth its length
so,
the perimeter is 10 meters more than twice its length
we know that
perimeter =2(L+W)
so, we get
now, we can simplify it
subtract both sides by 2L
now, we can find L
subtract both sides 3
multiply both sides by 4
so,
length of rectangle is 8 meter
width of rectangle is 5 meter ............Answer
