Answer: 23

step by step:

The angle is 90 degrees

(2x+14) + (x+7) = 90

(2x+ x) + (14+7) = 90

3x+21 = 90 (subtract 21 from both sides)

3x+ 21 - 21 = 90 - 21

3x = 69 ( divide each side by 3)

x = 23

A triangular flag has an area of 493 square meters and a height of 17 meters. What is the length of the base
ahrayia [7]

Answer:

\frac{984}{17} or around 57.88

Step-by-step explanation:

We can find the base length by using the formula for the area of a triangle.

A=\frac{bh}{2}

Plug in the values that we know, the area and the height, and solve for b.

493=\frac{17b}{2}

984=17b

b=\frac{984}{17}So the base is [tex]\frac{984}{17} or about 57.88 if you round to the nearest hundredth.

The measure of an angle is 60° less than nineteen times the measure of its supplement. what is the measure of the angle?
DerKrebs [107]
Two angles are supplementary when they <span>add up to 180 degrees.

x = angle
19x-60 = </span><span>supplement angle

x + 19x - 60 = 180
20x = 180 + 60
20x = 240
x = 240/20
x = 12</span>°  ← answer

EastWind [94]

Answer: 20.48

Step-by-step explanation:

use the pythagorean theorem for the diagnal sides

3^2+3^2=c^2

9+9=c^2

18=c^2

\sqrt{18}

this gives you 4.24

now add 6+6+4.24+4.24 to get 20.48
