Question

What is the approximate value of y − x?

A) 4.9°
B) 6.2°
C) 11.1°
D) 17.2°

Answer 1

D is your answer!!!!!!!!!!!

Answer 2

In right triangle LMN are given the lenghts of two legs. You can find the value of
`\tan x` and
`\tan y` and then estimate the difference y-x.

1.

`\tan x=(LM)/(LN)=(14.1)/(19.1)=(141)/(191),\\ \\x=\arctan (141)/(191)\approx 36.4^(\circ).`

2.

`\tan y=(LN)/(LM)=(19.1)/(14.1)=(191)/(141),\\ \\y=\arctan (191)/(141)\approx 53.6^(\circ).`

Then

`y-x=53.6^(\circ)-36.4^(\circ)=17.2^(\circ).`

Answer: correct choice is D
