Answer:

Part A: 6

Part B: 6√3

Step-by-step explanation:

Part A:

Since one angle measures 30°, and another angle is a right angle measuring 90°, the third angle measures 60°.

In a 30-60-90 the short leg is half of the hypotenuse.

YX = 12/2 = 6

Part B:

Method 1:

In a 30-60-90 triangle, the length of the long leg is √3 times the length of the short leg.

YZ = 6√3

Method 2:

Use the Pythagorean theorem.

a² + b² = c²

6² + (YZ)² = 12²

(YZ)² = 108

YZ = √(108)

YZ = √(36 × 3)

YZ = 6√3

  • sin30=XY/XZ
  • 1/2=XY/12
  • XY=6

#B

  • Cos30=YZ/XZ
  • √3/2=YZ/12
  • YZ=6√3

Another way is using Pythagorean theorem

  • YZ²=XZ²-XY²

In a litter of 7 kittens, each kitten weighs less than 3.5 ounces. Find all the possible values of the combined weights of the k
Dima020 [189]

Let's use w to symbolize the weight of kittens. Given by the statement "each kitten weighs less than 3.5 ounces" we know that

1*w < 3.5

We can multiply both sides of the inequality by 7 to determine the total weights

7*(1*w) < 7*(3.5)

7*w < 24.5

Since there are 7 kittens, the combined weight of the kittens is 7w, therefore the above expression could be read as "The combined weight of the kittens is less than 24.5 ounces"
