Question

Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth.

A. x = 5.7, y = 6.9
B. x = 6.9, y = 5.7
C. x = 11.3, y = 8
D. x = 8, y = 11.3

Answer 1

same as previous question.
just numbers are different
first try it by yourself

Answer 2

ughh okay .. x is hypotenuse , y is adjacent and 8 is opposite

Answer 3

or 8 is adjacent and y is opposite? @hartnn

Answer 4

@shubhamsrg Yay! you're here!!! ^_^

Answer 5

x is hypotenuse , y is adjacent and 8 is opposite
is correct

Answer 6

now fin
sin 45 =...
cos 45 =..

Answer 7

Do you know the property that sides opposite to equal angles are equal ?

Answer 8

sin 45 = .707
cos 45= .707

Answer 9

yes
and sin 45 = opposite side/ hypotenuse = ... ?

Answer 10

sin 45 = 8/x

Answer 11

correct
so x = ... ?

Answer 12

x=5.656 ?

Answer 13

x= 8/.707 = ... ?

Answer 14

Ohh sorry i multiplied

Answer 15

x=11.315

Answer 16

yes
to find y
you can use
tan 45 too
its easier

Answer 17

1?

Answer 18

yes!
and tan 45 = opp. side/ adjacent side = ...

Answer 19

tan 45 = 8/y

Answer 20

y=8?

Answer 21

correct!

Answer 22

also remember that legs of a 45 , 45 triangle are equal :)
