The measure of angle A in ABC is twice the measure of angle B and the measure of angle C is 20° less than the measure
diamong [38]

Answer:

m∡A = 100°

m∡B = 50°

m∡C = 30°

Step-by-step explanation:

let 'x' = m∡B;  50°

let '2x' = m∡A;   100°

let 'x-20' = m∡C;   30°

x + 2x + x - 20 = 180

4x - 20 = 180

4x = 200

x = 50

Mr. Lewis designed a circular walkway in
NARA [144]

Answer:

The diameter is equal to the circumference divided by the number pi

Step-by-step explanation:

we know that

The circumference of the circular walkway is equal to

C=\pi D

where

D is the diameter

we have

D=6\ ft

substitute

C=\pi (6)

C=6\pi\ ft

so

Divide the diameter by the circumference

\frac{D}{C}=\frac{6}{6\pi}

\frac{D}{C}=\frac{1}{\pi}

D=\frac{C}{\pi}

The diameter is equal to the circumference divided by the number pi

Solve the following inequality algebraically. ∣x−5∣≤11
Igoryamba

Answer:

-6\leq x\leq 16

Step-by-step explanation:

So we have the inequality:

|x-5|\leq 11

Definition of Absolute Value:

x-5\leq 11\text{ or } x-5\geq -11

Note that the sign is flipped in the second case because we multiplied by a negative.

Add 5 to both sides to both equations:

x\leq 16\text{ or } x\geq -6

Merge:

-6\leq x\leq 16

And we're done!
