In the diagram below, the measure of angle CAB is equal to 3 + 17 and the measure of angle DAB is equal to 2 + 12. If the measure of angle CAB is 119°, what is the value of ?

c

step-by-step explanation:

at least i think its

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
