Question

In the triangle below, determine the

Answer 1

angle A

Answer 2

use trigonometry
tan A = 15 / 7

Answer 3

tan A= 2.1428571428571428571428571428571 but then what?

Answer 4

lol - I don't think you need the value to that number of decimals!!!!

Answer 5

lol, but after the tan A= 2.14, is that it?

Answer 6

start with
tan A = 15 / 7
then take the inverse tan of both sides
tan -1 (tan A) = tan -1 (15 / 7)
A = tan -1 (15 / 7)
tan -1 is an inverse tan. you know how to do that on your calculator?

Answer 7

use your calculator to find the angle whose tangent is 2.1429 to get a pretty accurate value

Answer 8

thanks
