Question

What is the area of △ABC ? Enter your answer, as a decimal, in the box. Round only your final answer to the nearest tenth. units² Triangle A B C has leg A C labeled 10 and leg B C labeled 17. Angle A C B is labeled 25.1 degrees.

Answer 1

Answer:
`36.1\ units^2`

Explanation:

You need to use the SAS area formula. This is:

`A=(a*b*sin(\alpha))/(2)`

Given the triangle ABC, you know that:

`a=AC=10\ units\\b=BC=17\ units\\\alpha=\angle ABC=25.1\°`

Therefore, substituting these values into the formula, you get that the area of the triangle ABC is:

`A=((10\ units)(17\ units)*sin(25.1\°))/(2)\\\\A=36.1\ units^2`
