In the figure above, lls, m 3 = (3x-105)º and
mz6=(2x+10)°
What is the m<8?
A. 55°
B. 60°
C. 120°
D. 125°

a

Step-by-step explanation:

first step is to set up an equation : 3x-105+2x+10=180

second step is to add like terms : 5x-95=180

third step is to add 95 to both sides: 5x=275

last step is divide 275 ( 180 + 95 ) by 5

47

step-by-step explanation:

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
