a = 3 ft
<u><em>Explanation:</em></u>
The relation between the legs and the hypotenuse of a right-angled triangle can be expressed using the Pythagorean theorem as follows:
<u>In the given triangle, we have:</u>
leg1 = 8 ft and hypotenuse = ft
<u>Substitute with the givens in the above equation to get the length of the second leg as follows:</u>
()² = (8)² + (second leg)²
73 = 64 + (second leg)²
(second leg)² = 9
either second leg =
or second leg = as length cannot be negative
Hope this helps :)
Answer:
<h2>(55/27, 32/9)</h2>Step-by-step explanation:
The system of equations is
The first step is to arrange like terms in colums, which is already done.
Then, we need to multiply a number by one equation in such way where we get opposite like terms. Notice that we need to multiply the first equation by -1
Then, we sum equations to obtain the value of one variable.
Now, we use this value to find the second variable
Therefore, the solution is (55/27, 32/9).
