Answer:
<h2>
x = 67°</h2>
Step-by-step explanation:
The sum of measures of angles in triangle is allways 180°
So:
x + 53° + 60° = 180° {subtract 113° from both sides}
x = 67°
You need to form an algebraic equation. 4.5+h=7.3 therefore h= 7.3 - 4.5 when you take 4.5 to the other side it becomes negative therefore the answer is 2.8.
Answer:
its the second answer!
Step-by-step explanation:
LHS: =

(using

)
We know

so we can replace the sin²x in the LHS expression as follows

which is the RHS.
