| Bisector AK is drawn in triangle ABC find the angles of the triangle if the angle BAK is 47 degrees and the angle AKC is 103.
Given:
triangle ABC,
AK – bisector,
angle BAK = 47 degrees,
AKC angle = 103 degrees.
Find the degree measures of angle B, angle A, angle C -?
Solution:
1) Consider the triangle ABC.
angle A = 2 * 47 = 94 degrees;
2) Consider the triangle AKC. We know that the sum of the degree measures of any triangle is 180 degrees. Consequently:
angle С = 180 – (angle KAC + angle AKC);
angle C = 180 – (103 + 47);
angle C = 180 – 150;
angle C = 30 degrees;
3) Consider the AKB.
angle B = 180 – (94 + 30);
angle B = 180 – 124;
angle B = 56 degrees.
Answer: 94 degrees; 30 degrees; 56 degrees.
