Room temperature is about 68 degrees fahrenheit (f). what is that temperature in celsius (c)? 9/5 c + 32 = f (9/5 is a fraction)

The temperature in Celsius (C) is, 20 degree

Step-by-step explanation:

As per the statement:

Room temperature is about 68 degrees Fahrenheit (F).

⇒F = 68 degree

Given the equation:

then;

Subtract 32 from both sides we have;

Divide both sides by we have;

degree

Therefore, the temperature in Celsius (C) is, 20 degree

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
