Question

In Triangle ABC, the measure of angle B is 45 degrees, and the measure of angle C is 60 degrees. Calculate the measure of angle A in Triangle ABC. Use math to explain and justify your solution. a) A = 75 degrees b) A = 90 degrees c) A = 30 degrees d) A = 120 degrees

Answer 1

To find the measure of angle A in Triangle ABC, subtract the measures of angles B and C from 180 degrees.

Step-by-step explanation:

To find the measure of angle A in Triangle ABC, we can use the fact that the sum of all angles in a triangle is always 180 degrees. Since we know the measure of angle B is 45 degrees and the measure of angle C is 60 degrees, we can subtract those angles from 180 to find the measure of angle A.

A = 180 - B - C

A = 180 - 45 - 60

A = 75 degrees
