Answer:
A = 50
B = 20
C = 110
Step-by-step explanation:
A triangle is equal to 180°
In order to find the measure of each angle, add angle A, B, and C to get 180°
If angle A = 5x, angle B = 2x and angle C = 110 then 5x + 2x + 110 = 180°
To find each angle, first solve for x:
5x + 2x + 110 = 180° start by adding like terms
7x + 110 = 180° now subtract 110 from 180
7x = 70 finally divide 7 from 70
x = 10
To find each individual angle, substitute x with 10. For example:
A = 5x
A = 5(10)
A = 50
B = 2x
B = 20
C = 110
If you were to add A, B, and C it should equal 180°
110 + 20 + 50 = 110
