Answer:
21/35
Step-by-step explanation:
Given :
- A right angled triangle with sides 28 , 35 ,21 .
And we need to find the value of cos A. We know that cosine is the ratio of base and Hypotenuse. So that ,
cos A = b/h
cosA = 21/35
<u>Hence </u><u>the</u><u> </u><u>required</u><u> </u><u>Answer</u><u> </u><u>is </u><u>2</u><u>1</u><u>/</u><u>35</u><u>.</u>

The volume of a cuboid toy chest is equal to their product of the length,
width, and height.
- The correct option for the toy chest she should purchase is; <u>Only toy chest A will provide the necessary storage space</u>.
Reasons:
The dimensions of the toy chest are;
Toy chest A;
Length = 5 feet
Width = 4 feet
Height = 2 feet
Toy chest B;
Length = 4 feet
Width = 2 feet
Height = 4 feet
Volume of Toy chest A = 5 ft. × 4 ft. × 2 ft. = 40 ft.³
Volume of Toy chest B = 4 ft. × 2 ft. × 4 ft. = 32 ft.³
The volume of the toy chest Mrs. Smith needs = 35 ft.³
The toy chest Mrs. Smith should purchase is Toy chest A, that has a volume of 40 ft.³, which can store items that with a volume of 35 ft.³
The correct option is; <u>Only toy chest A will provide the necessary storage space</u>
