1. Question 1: In a triangle ABC, if LA = 50° and LB = 60°,find LC. 2. Question 2: In a triangle PQR, LP =90°,and ZQ = 45°. What is the measure of LR? 3. Question 3: The angles of a triangle are in the ratio 2:3:4. Find the measure of each angle.
Answer (2)
The sum of the interior angles of a triangle is always 180 degrees. If two side (side A and side B) are given, simply subtract from the total degrees, 180.side A + side B + side C = 180 50 degrees + 60 degrees + side C = 180110 degrees + side C = 180side C = 180 - 110side C = 70 degreesQuestion 2: LR = 45 degrees
Answer:angle A = 40°angle B = 60°angle C = 80°Step-by-step explanation:ratio of the angles = 2:3:4total = 2+3+4 = 9 A+B+C= 180°@angle A: 2(180°)/9 = 40°
