Given:
The base of the triangle = 8.6 yd
The height of the triangle = 10.9 yd
To find the area of the triangle.
Formula
The area of a triangle with b as base and h as height is
Now,
Taking, b= 8.6 and h = 10.9 we get,
sq yd
or, 
sq yd
Hence,
The area of the given triangle is 46.87 sq yd.
y = mx + b
5 = 12(-3) + b
5 = -36 + b
b = 41
y = -3x + 41
3x - 5 1/2 is the expression
6) arc length = 2*PI*R* degree/360
arc length = 2 * PI * 3 * 65/360
= 6*PI x 65/360
= 13/12*PI
Answer = C
7) drawing the lines as given would make a T shape with B being the mid point, so the answer would be C
