First, we have to solve the sides of the right triangle by using the Pythagorean theorem: a² + b² = c² where c is the length of the hypotenuse. Then, we can use the legs as length and height of the triangle and find the area by 1/2(base x height).
x² + 60² = 68²
x² + 3600 = 4624
x² = 1024
x = √1024
x = 32 = length of the other side
A = (1/2)(32) (60) = 960 mm²
The correct answer is:
D. 20.4 cm - 16.8 cm (attached)
The triangular prism is similar to the described prism.

X-2 = 4+x
+2 +2
x = 6+x
-x -x
0 = 6
Answer: no solution / empty set / ∅
Answer:
Step-by-step explanation:
In vertex form, the equation is
y = a(x-h)^2 + k
So just read off the values!
