Step-by-step explanation: We are given to find the value of x from the following trigonometric equation:
sin55=cosx
We know that the sine of any acute angle is equal to the cosine of its complement and cosine of any acute angle is equal to the sine of its complement.So, from equation (i), we get
sin55 ∘ =cosx
⇒sin55 ∘ =sin(90 ∘−x)
⇒55 ∘ =90 ∘ −x
⇒x=90 ∘ −55 ∘
⇒x=35 ∘
Thus, the required value of x is 35°.
Answer: $38.50
Step-by-step explanation: Find 70% of $55.
9.1 or 9 rounding
Step-by-step explanation:
This is known because 26x0.65 is 16.9. then we subtract 16.9 from 26 which gives us 9.1.
