Find the area of the triangle on problem #7 and what statement in true for the triangle on #8

Mathematics
1 answer:
Reptile [31]4 years ago
3 0

Answer:

Step-by-step explanation:

Using the pythagorean theorem, a^2+b^2=c^2

32/2=16, 20 would be the hypotenuse, so it would be 20^2-16^2=a^2 because we want to find the middle line. 400-256=144. sqrt(144) = 12.

Then since it is an isosceles triangle, we can simply do 12*16=192

The answer for 7 is 192ft^2

For #8, the answer is short leg * sqrt(3) = long leg

On another note, you can find the hypotenuse of a 30-60-90 triangle by doubling the shortest leg

-1\2x+1y=3/4, y-2x=3 , do I divide all the  fractions by 4 to get rid of the fraction  or by 2?
Law Incorporation [45]
You <em>multiply</em> both sides of the first equation by  4.
Then you have . . .
                            -2x + 4y  =  3     and     y - 2x  = 3 .

If you want to get rid of a fraction, you multiply it by itsdenominator.
BUT ... whatever you do to one term on one side of the equation, you
have to do the same to <em>all</em> the terms on that side, AND then you have to
do the same thing to all the termson the OTHER side.
