Which value is equivalent to sin20°?
AveGali [126]

Answer:

Option C. cos70°

Step-by-step explanation:

we know that

If two angles are complementary, then the sine of one angle is equal to the cosine of the other angle and the cosine of one angle is equal to the sine of the other angle

Remember that

Tow angles are complementary , if the sum of their angles is equal to 90 degrees

so

If A+B=90°

then

sin(A)=cos(B)

cos(A)=sin(B)

In this problem we have

A=20°

B=90°-20°=70°

therefore

sin(20°)=cos(70°)

cos(20°)=sin(70°)

A pet store sold 36 Siamese cats. If the ratio of Siamese cats to house cats sold was 4:9, what is the combined amount of cats s
Dafna11 [192]

 The combined amount of cats sold is 117.

Ratio expresses the relationship between two variables. It shows the frequency of which that one value is contained within another variable.

The ratio of  Siamese cats to house cats = 4 : 9

Number of Siamese cats = 36

Number of combined cats = c

This equation can be formed using the above information:

4/13 x c = 36

4c = 468

c = 468 / 4

c = 117
