Answer:
sin(x) and cos(y) are equal and have ratio of 1 : 1
First find the missing hypotenuse using Pythagoras theorem:
a² + b² = c²
12² + 5² = c²
c = √144+25
c = 13
using sine rule:
using cosine rule:
The answer to the question is 112°
First, you must set up an equation to find x.
Then, you must use distributive property to simplify the parentheses.
Next, add like terms.
Then, subtract 20 on each side.
Next, divide 10 on each side.
Now, you must substitute 34 in for x.
When we are reducing we divide numerator and denomerator by the same number.
