Step-by-step explanation:
Given:
Right ∆ with,
Hypotenuse = x
Opposite = 9
Reference angle
= 39°.
Required:
The value of x
Solution:
Since we are given a reference angle with opposite length, and we are to find the hypotenuse length, x, apply the following trigonometric ratios formula:
Plug in the values into the equation
Multiply both sides by x
Divide both sides by sin(39)
Ответ:
As we know that a type of chemical reaction in which two elements as reactants:
C(s) + O2(g) ∆> CO2(g)
Here, ∆ = Heat Energy.
Here, reactants = C(s) + O2(g)
and, product = CO2(g)
This type of reaction is known as combination reaction. It is also known as addition reaction.
