What is the length of the hypotenuse of the triangle?

√22

√33

√57

√65

answer:

hypothenus = √65

Step-by-step explanation:

using pythagoras theorem

hypothenus² = opposite²+ adjacent²

hypothenus² = 7² + 4² = 49 +16 = 65

hypothenus = √65

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°

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
