Evaluate radical expression challenge

8

Step-by-step explanation:

Using the rules of exponents

= and =

Given

=

= = = 8

1 and 5/647 or 1.00779

Step-by-step explanation:

10x64+7=647

5x64+1=642

647/642=1.00779

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°
