The area of a right triangle is 30 ft2. the base of the triangle is 12 ft. what is the length of the hypotenuse? show

The height is 5ft

Step-by-step explanation:

We know the area is 30ft^2 and the base is 12 ft.

Plug that information in the formula for the area of a triangle,

Formula for area of a triangle:

A = (1/2)bh  (area is one half of the product of    the base and height)

The question gives us A = 30, and b = 12.  We can plug them in and find h

30 = (1/2)(12)h

Now solve for h

  30 = 6h         (1/2)(12) means '12 times one half' or 'half of 12' which is 6

  5 = h              (30 divided by 6 is equal to 5)

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
