I think the correct answer from the choices listed above would be the third option. The statement that best describes the gas in a scuba tank would be that <span>the gas is compressed. The gas inside is exposed in a very high pressure which compresses it to liquid.</span>
90x+120 is equivalent to 30 (3x+4)
Answer:
The drawing in the attached figure
see the explanation
Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal interior angles
In this problem
we have an isosceles triangle (because has two equal interior angles)
see the attached figure to better understand the problem
step 1
Find the length side AB
In the right triangle ABD
----> by CAH (adjacent side divided by the hypotenuse)
we have
---> because is an isosceles triangle (the height bisect the base)
substitute
Find the length side AC
we know that
AC=AB ----> by definition of isosceles triangle
so
step 2
Find the perimeter
step 3
Find the height AD
In the right triangle ABD
----> by TOA (opposite side divided by the adjacent side)
substitute the given values
Find the area of triangle
substitute
