Answer:

Option D

180\°< \theta < 270\°

Step-by-step explanation:

we know that

If sin(\theta)

then ------> the angle could be in the III or IV quadrant

If tan(\theta) >0

then -----> the angle could be in the I or III quadrant

so

The angle belong to the III quadrant

therefore

180\°< \theta < 270\°

Lyrx [107]
a. CPCTC is your answer

CPCTC means that "Congruent Parts of a Congruent Triangle(s) are Congruent"

If ΔBRM ≅ ΔKYZ (given), then every part inside the triangle is ≅ with the corresponding side.
So, for example Line BR will be ≅  with Line KY, etc

A sample of men's heights was taken and the mean was 68.8 inches. The standard deviation is 2.8 inches. What percent of the men
jarptica [38.1K]

Answer:

87.29%

Step-by-step explanation:

Given: Mean= 68.8 inches

           Standard deviation= 2.8 inches

           

Now, finding the percent of the men in the sample were greater than 72 inches.

We know, z-score= \frac{x-mean}{standard\ deviation}

z-score= \frac{72-68.8}{2.8}

⇒ z-score= \frac{3.2}{2.8} = 1.14

∴ z-score= 1.14

Next, using normal distribution table to find percentage.

Coverting 0.8729 into percentage= 0.8729\times 100

We get the percentage as 87.29%

Hence, 87.29% of the men in the sample were greater than 72 inches.

Naya [18.7K]

Answer:

13.4feet

Step-by-step explanation:

The set up forms a right triangle.

Given

Height of the staircase h = 12 feet

Base of the stairs b = 6feet

Required

Length of the ramp l

Using the pythagoras theorem

l² = h² + b²

l² = 12²+6²

l² = 144 + 36

l² = 180

l = √180

l = 13.42 feet

Hence the length of the ramp to the nearest tenth is 13.4feet
