Find Angle B tri{}{90}{}{}{}{}

Problem

Find Angle *B* in a right triangle where *C=90

Solution

1. Identify the properties of a triangle. The sum of the interior angles of any triangle is always 180

2. Set up the equation for the sum of the angles A B and C

A+B+C=180

3. Substitute the known value for the right angle, C=90 into the equation.

A+B+90=180

4. Isolate the variable B by subtracting 90 and A from both sides of the equation.

B=180−90−A

5. Simplify the expression to find the relationship between the two acute angles.

B=90−A

Final Answer

B=90−A
