Answer:1.) m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2.) 24° + x + m∠C = 180°
3.) x = 156° - m∠C
Step-by-step explanation:
1. m∠A +m∠B +m∠C = (sum of angles in a triangle △)
2. 28°+x−4° + ______ = 180°
24° + x + m∠C = 180°
3) x = 180° - 24° - m∠C
x = 156° - m∠C
(3x+3) + (4x + 2)
------------------------- = 13
2
13(2) = (3x+3) + (4x+2)
26 = 3x + 3 + 4x + 2
26 = 7x + 5
26-5 = 7x
21 = 7x
x = 21 ÷ 7
x = 3
