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

Solve for x −9x+5≤17 OR 13x+25≤−1
arsen [322]

Answer:

(-∞ 2] ∪ [-4/3 ∞ )

Step-by-step explanation:

Given compound inequality,

-9x+5\leq 17\text{ or }13x+25\leq -1

-9x\leq 12\text{ or }13x\leq -26  ( Subtraction property of inequality )

-x\leq \frac{12}{9}\text{ or }x\leq -\frac{26}{13}   ( Division property of inequality )

-x\leq \frac{4}{3}\text{ or }x\leq -2

x\geq -\frac{4}{3}\text{ or }x\leq -2   ( a < b ⇒ - a > - b )

Hence, the solution of the given inequality is,

(-∞ -2] ∪ [-4/3 ∞ )

A sandbox has a perimeter of 21 1/2 feet. If the length is 5 1/4 feet, what is the area of the sand box?
LiRa [457]
The perimeter of a rectangle is twice the sum of length and width, so the sum of length and width is half the perimeter, 10 3/4 ft.

The width will be the difference between this and the length, hence 5 1/2 ft.

The area is the product of length and width.
  A = length×width
  A = (5.25 ft)×(5.5 ft) = 28.875 ft²

The area of the sandbox is 28 7/8 ft².
