The base of a triangle is 18in. The height is 10in. What is the area of the triangle?

Hello it has been a long time since I did this.  

The formula is bxhx1/2=

18x10x1/2

180x1/2

90

* If it is easier you can just do divide by 2*

90in²

Step-by-step explanation:

Area of a triangle, A = 1/2 x base x height

We are given, base = 18in

Height = 10in

Therefore, A = 1/2 x 18in x 10in

= 90in²

The area of the triangle with base 18in and height 10in is 90in²

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
