First, look into my attachment
∠A = ∠C
2m = 70°
m = 70°/2
m = 35°

The sum of angles inside parallelogram is 360°
∠A = ∠C
∠B = ∠D

∠A + ∠B + ∠C + ∠D = 360°
70° + n + 70° + n = 360°
140° + 2n = 360°
2n = 220°
n = 110°

m=70/2=35

n=(360-70*2)/2=110

Morgan is reupholstering an old chair with two circular cushions. Each cushion has a circumference of 7. 85 feet. He will need t
kramer

The total fabric Morgan needs to cover the cushions will be 19.64 square feet.

It is given that each cushion has a circumference of 7.85 feet.

It is known that the circumference of a circle = 2πr, where 'r' is the radius of the circle.

2πr = 7.85

r = 1.25

<h3>What is an area of a circle?</h3>

area of a circle is πr².

now, we can calculate the area = π× 1.25² = 4.91 square feet

since each circular cushion has two circular faces so the total number of faces Morgan needs to cover will be 4.

Therefore, the total fabric needed= 4×4.91 = 19.64 square feet.

Determine if the following equations are equal by evaluating both sides
padilas [110]

Answer:

Yes, the both sides of the given equation are equal.

Step-by-step explanation:

The given equation is

\log((1-i)^3)=3\log(1-i)

Taking LHS,

LHS=\log((1-i)^3)

Using the power property of logarithm, we get

LHS=3\log(1-i)                               [\because log_ax^n=nlog_ax]

LHS=RHS                                   [\because RHS=3\log(1-i)]

Both sides of the given equation are equal.
