Question

If one angle of a triangle is greater than other two angles by 30° then the angles of the triangle are (1 Point) a. 30 degree, 30 degree,120 degree b. 50 degree,50 degree,80 degree c. 40 degree,40 degree,100 degree

Answer 1

Step-by-step explanation:

Example

Step 1 The two sides we know are Adjacent (6,750) and Hypotenuse (8,100).

Step 2 SOHCAHTOA tells us we must use Cosine.

Step 3 Calculate Adjacent / Hypotenuse = 6,750/8,100 = 0.8333.

Step 4 Find the angle from your calculator using cos-1 of 0.8333
