Question

Given that m angle BAC=48^ and m angle BCA=19^ , find m angle ABD

Answer 1

Answer:

m<ABD is 113 degrees

Step-by-step explanation:

The interior angles of a triangle must add up to 180 degrees.

Representing angle ABD by x, we have:

x + 48 degrees + 19 degrees => x + 67 degrees = 180 degrees.

Subtracting 67 degrees from boths sides, we get x = 113 degrees.

m<ABD is 113 degrees.

Answer 2

Answer:

B. 67°

Step-by-step explanation:

Step 1: Find m∠B

180 - (48 + 19) = 113°

Step 2: Use Supplementary Angles rules

180 - 113 = 67°
