I’m struggling to solve questions one and two because i’m unsure of how to round to the nearest quarter hour and adding the hours per day. !

m∠a is 90°

m∠b is 40°

4

step-by-step explanation:

im pretty sure it's 4 beacsue 8/2 equals 4

answer: 30

step-by-step explanation: its 30 because im a basketball player and stephen curry hits most of his shots so if you put 30 you might make the shot goodluck

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
