Pls help me i need it to move on i did so many i cant figure it out.

B between 200 to 400 o

B. Between 200 and 400

Step-by-step explanation:

Rule of exponents means that you can subtract when they are divided

-5+7=2

7.8*10^2/3.1

Simplify

780/3.1= 251.612903

okay so 15.15 *()5: +5/6

step-by-step explanation:

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°
