Find the x-intercept of y =× -3

X-intercept takes place when y=0: what is the value of x so that y=0?

y=x-3

y=0 => x=3.

So, the X-intercept point is (3, 0)

we know that

applying the law of sines

°

so

∠j=18°

∠k=29°

∠l=180-(18+29)=133°

the answer part a) is

the measure of angle k is  ≈29°

part b)  the measure of angle k could also be

(180-29)=151°

so

∠j=18°

∠k=151°

∠l=180-(18+151)=11°

the answer part b) is

the measure of angle k could also be 151°
