ab reperesent the 2 legs u cannot use the hyp
You can use any but i'll use the first one
==> 
==>
==> 832.5 is the answer
Answer:
(7-5i)( 2+3i)
=7(2)+ 7(3i)-5i(2) -(5i)(3i)
= 14 +21i -10i +15
= 29 +11i
Hi there!
In order to solve, you can use substitution. This means that you use one equation and solve for one variable, then use that one equation and plug it into the other equation. Here's how we'd do it:
WORK:
x = 12 - y (since x is already solved for, we'll use that to plug into the other given equation.
2(12 - y) + 3y = 29 (using substitution)
24 - 2y + 3y = 29
24 + y = 29
y = 5
Plug the value of y back into the first equation
x = 12 - 5
x = 7
ANSWER:
A - x = 7, y = 5

<u>Given</u><u>:</u><u>-</u></h3>
Area of a square game board = 179 inches ²
<h3>
<u>To</u><u> </u><u>be</u><u> </u><u>calculated</u><u>:</u><u>-</u></h3>
Calculate the side of given square game board.
<h3 /><h3>
<u>Formula</u><u> </u><u>applied</u><u>:</u><u>-</u></h3>
Area of square = ( Side )²
<h3>
<u>Solution</u><u>:</u><u>-</u></h3>
We know that,
Area of square = ( Side )²
★ Substituting the value in the above formula, we get :
=> 179 = ( Side )²
=> Side = √179
=> Side = 13.37 inches ( approx )
An hour is 60 mins long. 30 mins is half of it. If we take 12 miles in an hour, divide it by 2, it will be 6 miles in 30 mins, and if we take 8 miles, divide it by 2, it would be 4 miles in 30 mins. Since the questions telling us how far apart are north cyclists, we’re adding 6 and 4 to get 10 miles. In conclusion, both cyclists are 10 miles apart. I might be wrong, but that’s the best I can do.
