Find the lengths of the missing sides in the triangle. Write your answers as integers or as decimals rounded to the nearest tenth. The diagram is not drawn to scale.

Question

The diagram shows 7 3 45 and then x

And my answer is 2.2 but that doesn't sound right to me..

Answer 1

Wait wait, there's no three. What I thought was a three was a y

Answer 2

You will have to do a better job of describing your triangle.

What are the lengths of sides given?
Is there an angle given?

Answer 3

its 1 day later and still no answer, bummer

Answer 4

/\
7 / \ y
/ \
/____45\
x

tried my best, but there's the graph

Answer 5

Although this might be late for the one who asked the question, I hope this answer helps the ones that will need help later on.

To answer the question, we are given the sides, 7, x, and y. We can use the sine and tangent of the 45-degree angle to find the missing sides.
Sin 45 = 45 7/x
X = 7/sin 45
Using a calculator, the answer would be rounded to 9.9.

Tan 45 = 7/y
Y = 7/tan 45
Using a calculator again, the answer would be 7.

X = 9.9
Y = 7
Hope this helps :)

Answer 6

Sorry, I messed up for the sin of 45.
It's not sin 45 = 45 7/x, it's:
sin 45 = 7/x
