If 13 is added to a number and the sum is multiplied by 3, the result is 7 times the number decreased by 9. Find the number. (Hint: part of the left hand side of the equation is in parentheses.) *

answe

its a

step-by-step explanation:

true

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°
