The angles of a triangle always add up to 180°.
120 + x + 16 + x = 180
Add up the values.
136 + 2x = 180
Subtract 136 from both sides.
2x = 44
Divide both sides by 2.
x = 22
'Of' in math means 'multiplied by,' so the equation that we can set up is:
So your answer is 320.
Recall that
Dividing both sides by cosh²(x) gives
Also, recall the identity
Then
Answer:
Step-by-step explanation:
X^2=-y^2+10y+5
