Answer:
Step-by-step explanation:
Since we are in quadrant 2, sine is positive. Since sine is positive and cosine is negative, then tangent is negative.
Now I'm going to find the sine value of this angle given using one of the Pythagorean Identities, namely .
If given , then we have by substitution of .
Let's solve:
for .
Subtract 4/9 on both sides:
Simplify:
Square root both sides:
===========
Multiplying top and bottom by 3 gives:
I'm going to move the factor of -1 to the top:
Answer:
Step-by The scale factor is the ratio that determines the proportional relationship between the sides of similar figures. For the pairs of sides to be proportional to each other, they must have the same scale factor. In other words, similar figures have congruent angles and sides with the same scale factor.-step explanation:
First way is create an equation like this:
and calculating it.
Second way is to find 37% of each number and then add it
+
In both cases the result is 10.829
Calories proportional to grams
calories= k x grams
27 = k x 3
therefore constant k = 9
