Question

The angles of a triangle are arranged in ascending order of magnitude. If the difference
between two consecutive angles is 10° find the largest angle is
(A) 60°
(B) 100
(C) 50°
(D) 70°​

Answer 1

Step-by-step explanation:

Answer: Let the measure of three angles of the triangle be x degrees, (x + 10) degrees and (x + 20) degrees. It is known that the sum of three angles of a triangle is 180 degrees. Therefore, the measures of three angles of the triangle are 50 degrees, 60 degrees and 70 degrees.
