If angle b measures 25°, what is the approximate perimeter of the triangle below? a. 10.3 units b. 11.8 units c. 22.1 units
A. 10.3 units.
We have been given an image of a right triangle and we are asked to find the perimeter of our given triangle.
First of all, let us find the measure of angle C using angle sum property.
Now, we will use law of sines to find the length of segment AC and BC as:
Therefore, the perimeter of our given triangle is 10.3 units and option A is the correct choice.
