Answer:
Step-by-step explanation:
reference angle=(14 π)/11-π=(14-11)π/11=3π/11
Answer:
Perimeter = 70ft
Step-by-step explanation:
Area of a rectangle is:
area = (length * width)
150 = a * b
a = 6b
a = length
b = width
then:
150 = 6b*b
150 = 6b²
b² = 150/6
b² = 25
√b² = √25
b = 5ft
a = 6b
a = 6*5
a = 30ft
then:
perimeter of a rectangle is:
p = 2(a+b)
p = 2(30 + 5)
p = 2*35
p = 70ft
16 is the answer add all side door
Answer:
As an equation: 15 × x = -75
Solved: x = -5
Step-by-step explanation:
15*x = -75
= 
, Divide by 15 on both sides to solve for x
x=, The 15 in the numerator cancels out with the denominator
x= -5, because 75/15=5
