In triangle ABC, the measure of angle B is 18° more than twice the measure of angle A. The measure of angle C is 42° more than that of angle A. Find the angle measures. A: 30°, 78°, 42° B: 30°, 78°, 72° C: 33°, 84°, 63° D: 26°, 70°, 84°

B: 30°, 78°, 72

Step-by-step explanation:

Given a .

Let

As per question statement, is 18° more than twice of .

i.e

is 42° more than that of

To find:

The angle measures of the triangle = ?

Solution:

We can use the angle sum property of a triangle here to find the three angles of the triangle.

As per angle sum property, the sum of all the three internal angles is equal to .

i.e.

Therefore, the correct answer is:

B: 30°, 78°, 72

it’s supposed to be -4+45=41
