Question

How do you find the area of a triangleGHI, if `angleI = 15^@`, `g = 14.2` , and `h = 7.9`?

Answer 1

The height `k` of Triangle GHI with HI as its base can be found by

`"(Height)"=7.9sin(15^circ)`

The area `A` of Triangle GHI can be found by

`A=1/2"(Base)(Height)"=1/2cdot 14.2 cdot 7.9 sin(15^circ) approx 14.52`
