Jason had to replace the floor of a triangular portion of his dining room. The portion had a height that was twice as high as the base. If the total area of the portion he needed to replace was 16 square feet (16ft2),how long in feet was the base of the portion he needed to replace?

4 feet

Step-by-step explanation:

We know the the area of a triangle can be represented as .

Since the height is twice the base, we can substitute the value in as in the expression, making it . If the area is 16, we can make the equation

Now to solve for b.

Hope this helped!

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
