Find x 8^3 * 8^x= 8^7

x=4

Step-by-step explanation:

8^3 ×8^x =8^7

3+x=7

x=7-3

x=4

8^3×8^4 =8^(3+4)=8^7

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°
