Hey I’m sure it’s 4! Sorry if I’m wrong that’s quite confusing
Answer:
Angle 1= 147
Angle 2= 33
Step-by-step explanation:
(4a+7) + (a-2) = 180
4a+7+a-2=180
5a+5=180
5a=175
a= 35
plug in 35 for A to find measurements
4(35) +7 = 147
(35) -2= 33
17.25/7.5 = 2.3
2.3/0.5 = 4.6
Answer is 4.6 cm
4.6*0.5*7.5=17.25
