Solve for a and determine the measure of each angle:
2 answers:
(5a-23) + (4a + 44) + (2a + 16) =180
11a + 37 = 180
11a =180-37
11a = 143
a = 143/11
a= 13
Measure of each angle
(5a-23) = 5(13)-23=42°
(4a + 44) = 4(13) + 44=96°
(2a+16) = 2(13) + 16 = 42°
Answer:
a =13
Step-by-step explanation:
180= (44+16-23)+11a
143=11a
143÷11= 13
