Answer: if the base is 24

Area = (base x height)/2, thus height = 2 (area/base)

height = 2(192/24)

Which gives you 40

height = 16 cm

the height and half of the base will give you two identical rightangle halves of the triangle

use pythagorean theorem to get the length of the hypotenuse of the 2 identical halves

a^2 + b^2 = c^2

12^2 + 16^2 = c^2

144 + 256 = c^2

(square root)400 = c

20 cm = c

there are 2 of these hypotenuses in the original triangle, so add the base and the 2 "hypotenuses" to get the perimeter

P = 20 + 20 + 24

P = 64 cm

****the perimeter of the isosceles triangle is 64cm

A figure is composed of a semicircle and a right triangle. Determine the area of the shaded region. Use 3.14 for π and round to

Aliun [14]

Answer:

$A=9.5\ ft^2$

Step-by-step explanation:

we know that

The area of the shaded region is equal to the area of triangle plus the area of semicircle

$A=\frac{1}{2}bh+\frac{1}{2}\pi r^{2}$

we have

$b=4\ ft$

Find the height of the right triangle applying the Pythagorean Theorem

$5^2=h^2+4^2$

$h^2=9\\h=3\ ft$

The radius of the semicircle is half the height of triangle

$r=3/2=1.5\ ft$

substitute in the formula

$A=\frac{1}{2}(4)(3)+\frac{1}{2}(3.14)(1.5)^{2}$

$A=6+3.5=9.5\ ft^2$

An airplane flies 2700 miles to Los Angeles to NYC. When the plane flies back to LA, is it flying in a negative direction? use a

dolphi86 [110]

Answer:

Distance = abs(-1700)

Distance = 1700 miles

Step-by-step explanation:

NYC is located East of Los Angels.

The Airplane flies from Los Angeles to the left direction from NYC.

Which is negative direction.

Therefore, distance = -1700

Here the distance cannot be negative even though if it flies in negative direction.

Therefore, we use the absolute value.

The absolute value of a number is always positive.

So, distace = abs( -1700)

Distance = 1700 miles.

Hope this will help you understand the concept.

Thank you.

What is the value of x=2x + 9 = -27

Sergio039 [100]

<h3>I'll teach you how to solve 2x + 9 = -27</h3>

-----------------------------------------------------

2x + 9 = -27

Subtract 9 from both sides:

2x+9-9 = -27-9

SImplify:

2x=-36

Divide both sides by 2:

2x/2 = -36/2

Simplify:

x= -18

Your Answer Is x= -18

plz mark me as brainliest if this helped :)
