Answer:

Step-by-step explanation:

In a right angled triangle, we have perpendicular, hypotenuse and base.

The hypotenuse is the longest side and opposite to the right angle. the side having 90 degree angle is perpendicular.

Applying formulas we can find the values:

the formulas are : cos (Ф) = Base / hypotenuse

sin (Ф) = Perpendicular / hypotenuse

tan (Ф) = Perpendicular / Base

11. cos z

cos z = Base / hypotenuse

cos z = 12/15

12. cos C

cos C = base / hypotenuse

cos C = 38/45

13. tan C

tan C = Perpendicular/ Base

tan C = 40/30

14. tan A

tan A = Perpendicular/ Base

tan A = 21/20

15. tan C

tan C = Perpendicular/ Base

tan C = 12/35

16. tan X

tan X = Perpendicular/ Base

tan X = 30/40

17. sin Z

Sin Z = Perpendicular / Hypotenuse

sin Z = 35/37

18. sin z = Perpendicular / Hypotenuse

sin z = 30/50

A recipe requires ¾ cup of nuts for 1 batch of muffins. Write the number of batches of muffins that can be made using 7 ½ cups o
Ivahew [28]

Answer:

10 batches

Step-by-step explanation:

3/4 cups = 1 muffins

15/2 cups = x muffins

For x muffins,

3/4 × X = 15/2 × 1

3x × 2 = 15×4

6x = 60

Divide both sides by 6

6x/6 = 60/6

X = 10

Hence 10 batches of muffins will be made from 15/2 cups of nuts.
