nirvana33 [79]
The actual airplane wing is 24 times bigger than her first drawing. 
24*4=96

The actual airplane wing is 96 inches long.
96/12=8
The actual airplane wing is 8 feet long.

The scale of her advertisement is 10 in : 96 in.

That reduces to 5 in :48 in.

Mara thinks x< 6 will earn the highest score here.
Mamont248 [21]

This question was not correctly written

Correct Question

Mara thinks x ≤ 6 will earn the highest score here.

David thinks x < 6 will.

Who is correct?

Answer:

Mara is correct

Step-by-step explanation:

In the above question, we are given two inequality equations

1) Mara: x ≤ 6

2) David : x < 6

For David , x < 6 means the score which is represented by x is less than 6

For Mara, x ≤ 6 means the score which is represented by x is less than or equal to 6

Therefore, Mara is correct because x ≤ 6 will earn the highest score here.

Find tan0, cos0, and csc0, where 0 is the angle shown in the figure. Give exact values, not decimal approximations. BRANLIEST!!​
Setler [38]

Answer:

see explanation

Step-by-step explanation:

We require to find the third side of the triangle.

Using Pythagoras' identity

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

let x represent the third side, then

x² + 15² = 17², that is

x² + 225 = 289 ( subtract 225 from both sides )

x² = 64 ( take the square root of both sides )

x = \sqrt{64} = 8

Thus

tanΘ = \frac{opposite}{adjacent} = \frac{15}{8}

cosΘ = \frac{adjacent}{hypotenuse} = \frac{8}{17}

sinΘ = \frac{opposite}{hypotenuse} = \frac{15}{17}

cscΘ = \frac{1}{sin0} = \frac{1}{\frac{15}{17} } = \frac{17}{15}
