Answer:
The area is 52.6 square inches.
Explanation:
If you don't know base or height but you have info on a triangle, such as two sides and the angle in between, and a little bit of trig, you can find the area.
There's an SAS Trig Triangle area formula:
A = 1/2×side×side×sin
this works for two sides and the angle in between, which is exactly the info you have in your question.
A = 1/2(14)(8)sin70°
A = 56sin70°
A = 52.6 sq inches
