m∠G = m∠H = 50

m∠I = 80

Explanation:

Answer 2

m∠G = m∠H = 50

m∠I = 80

Explanation:

m∠H = m∠G {Isosceles triangle property}

5x - 5 = 3x + 17 {Subtract 3x from both sides}

5x - 3x - 5 = 17 {Combine like terms}

2x - 5 = 17 {Add 5 to both sides}

2x = 17 + 5

2x = 22

x = 22/2

x = 11

m∠H = 5x - 5

= 5*11 - 5

= 55 - 5

m∠H = 50

m∠G = m∠H = 50

m∠G + m∠H + m∠I = 180 {Angle sum property}

50 + 50 + m∠I = 180

100 + m∠I = 180

m∠I = 180 - 100

m∠I = 80
