An isosceles triangle has a base of 4 and a height of x+3. If the area is 10, what is the value of x?

1 answer:

5 0

The area of a <span>isosceles triangle:
S=(bh)/2, where b is for base (=4) and h is for height (=x+3)
We get the equation:
10=(4*(x+3))/2
10=(4x+12)/2
4x+12=20
4x=8
x=2

Select the correct answer.<br> Which graph shows a function and its inverse?

Anna007 [38]

I think it’s C because inverses are basically the reciprocals of each other. These make 90 degree angles and the slopes product should be -1. C looks like the lines are perpendicular so I would go with that

The area of a triangle is 1/2*base*height so 1/2*10*8 which is equal to 40in²
