Answer:
Step-by-step explanation:
Let the length be L
Formula
SA = 2Lw + 2Lh + 2wh
Givens
h = 15 cm
w = 6 cm
L = ?
SA = 684 cm^2
Solution
Substitue what you know into the given formula
2*6*L + 2*15*L + 2 * 6 * 15 = 684 Combine
12*L + 30*L + 180 = 684 Combine again
42L + 180 = 684 Subtract 180 from both sides.
42L +180 -180 = 684 - 180
42L = 504 Divide by 42
Answer: L = 12
<u>Given</u>:
The figure contains a right triangle.
The two angles of the triangle are 45° each.
The length of one leg is 3 units.
The length of the hypotenuse is x units.
We need to determine the value of x.
<u>Value of x:</u>
The value of x can be determined using the formula,
where , adj = 3 and hyp = x.
Substituting these values, we get;
Simplifying, we get;
Thus, the value of x is
