Question

Find the area of the triangle.
image of a triangle in which two sides are labeled 9 point 5 in and the third side 10 point 2 in; a dashed line originates in the corner formed by the two 9 point 5 in sides and extends to the 10 point 2 in side; a box is in the right corner where the dashed line intersects the 10 point 2 in side
48.45 in2
20.4 in2
40.8 in2
81.6 in2

Answer 1

Area = 1/2bh, where b is base and h is height. B and h must be at a right angle to each other.

Answer 2

Any ideas using this formula?

Answer 3

no idea at all

Answer 4

If you use the side that is 10.2 in long, then the height could be the dotted line.

Answer 5

So, Area=1/2*10.2*8 in^2

Answer 6

The box between that side and the doted line means the lines are at right anglesto each other.

Answer 7

*angles to

Answer 8

Can you calculate it now?
