Firstly we calculate the height(h)...,

by using trigonometry ratios

;tan 45° = h/5

;where.. h = 5 tan 45°

;h = 5

Then we calculate the side x...using the height h and the angle of 30°

by also using trigonometry ratios

; sin 30° = 5/x

;where.. x = 5/(sin 30°)

Hence...., x = 10

Answer: x = 10

What is the reciprocal of each mixed number? Drag and drop the answer into the box to match each number.
Gnoma [55]
Hi there!! 

First, we are going to find the improper fraction of each mixed number. 

10 1/3 >>>>> 10*3+1=31 31/3

2 2/3 >>>>> 2*3+2=8.      8/3 

5 1/3 >>>>>> 5*3+1 = 16.  16/3 

TO find the reciprocal, we switch the numerator with the denominator. 

31/3 changes to 3/31, 8/3 changes to 3/8, and finally 16/3 changes to 3/16. 


Your answer is: 

3/31
3/8
3/16

Hope this helps! Let me know if you have any questions:)
