Answer:

1. x=18, y=6\sqrt{10}

2. x=108, y=180

Step-by-step explanation:

The height of the right triangle drawn to the hypotenuse is the geometric mean of two segments of the hypotenuse (two legs' projections)

1. Use this property, so

CD^2=AD\cdot BD\\ \\6^2=2\cdot x\\ \\36=2x\\ \\x=18

Consider right triangle BCD. By the Pythagorean theorem,

BC^2=BD^2+CD^2\\ \\y^2=18^2+6^2\\ \\y^2=324+36\\ \\y^2=360\\ \\y=\sqrt{360}=6\sqrt{10}

2. Consider right triangleGM*. By the Pythagorean theorem,

G*^2=GM^2+M*^2\\ \\240^2=GM^2+192^2\\ \\GM^2=240^2-192^2=(240-192)(240+192)=48\cdot 432=144^2\\ \\GM=144

Use this property to find x:

GM^2=192\cdot x\\ \\144^2=192\cdot x\\ \\x=\dfrac{144^2}{192}=108

Consider right triangle GMCup. By the Pythagorean theorem,

y^2=x^2+GM^2\\ \\y^2=108^2+144^2\\ \\y^2=32,400\\ \\y=180

Evaluate the following expression if a=-9, b=-7,c=9 and d=3<br> 2cd + 3ab =
stepladder [879]

Answer:

<h3>The answer is 243.</h3>

Step-by-step explanation:

To evaluate the expression substitute the values of a , b , c and d into the above expression

a = - 9

b = - 7

c = 9

d = 3

So we have

2cd + 3ab = 2(9)(3) + 3(-9)(-7)

= 2(27) + 3( 63)

= 54 + 189

We have the final answer as

<h3>243</h3>

Hope this helps you

Find the area of the semicircle. diameter = 12
dimaraw [331]

Answer:

\huge\boxed{\sf Area\ of \ Semicircle = 56.55 \ units^2}

Step-by-step explanation:

Diameter = 12

Radius = 12/2 = 6

\sf Area\ of \ Semicircle =\frac{\pi r^2}{2} \\Area\ of \ Semicircle =\frac{\pi (6)^2}{2} \\Area \ of \ Semicircle = \frac{\pi (36)}{2}\\ Area \ of \ Semicircle = 18 \ pi

\sf Area\ of \ Semicircle = 56.55 \ units^2
