What is the measure of the largest angle of a triangle if the ratio of the measures of the three angles is 5:3:1

First Angle = 100°

Second Angle = 60°

Third Angle = 20°

Step-by-step explanation:

Step 1:

5 : 3 : 1            Ratio

Step 2:

5x + 3x + x = 180°          Sum of a Δ

Step 3:

9x = 180°          Combine Like Terms

Step 4:

x = 180° ÷ 9                 Divide

Step 5:

x = 20°

First Angle = 5 × 20° = 100°

Second Angle = 3 × 20° = 60°

Third Angle = 1 × 20° = 20°

Hope This Helps :)

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"

answer: a

step-by-step explanation: the answer is a due to the rule of symmetry; that a line of symmetry must divide a figure into 2 pieces that are the exact same, only reflected over a line of symmetry. b and c do not have lines of symmetry and would not divide the figure evenly, thus making the answer a.
