In ΔDEF, the measure of ∠F=90°, EF = 2.3 feet, and FD = 2.9 feet. Find the measure of ∠D to the nearest tenth of a degree.
Phoenix [80]

Answer:

\theta=38.42 \textdegree

Step-by-step explanation:

From the question we are told that:

Angle of F \angle F=90 \textdegree

Length of EF = 2.3 feet,

Length of FD= 2.9 feet,

Generally the equation for Angle D \theta is mathematically given by

Since \angle F=90.The triangle  is a right angle Triangle

Therefore

 tan \theta=\frac{EF}{FD}

 tan \theta=\frac{2.3}{2.9}

 \theta=tan^{-1} 0.793

 \theta=38.42 \textdegree

What is the slope and are they linear/perpendicular?<br> PHOTO ABOVE
Mandarinka [93]

Answer:

Slope of line 1 = 3

Slope of line 2 = 3

Slope of line 3 = -1/3

Line 1 and 2 are parallel

Line 1 and 3 are perpendicular

Line 2 and 3 are perpendicular

Step-by-step explanation:

Find the slope of each line by using this equation:

y_{2} - y_{1} / x_{2} - x_{1}

lines are parallel if they have the same slope and line are perpendicular in they have opposite reciprocal slopes. (-1/3 is the opposite reciprocal of 3).

Hope this helps!

sergij07 [2.7K]

There is 46% probability of experiencing neither of the side effects.

<h3>What is probability ?</h3>

Probability shows possibility to happen an event, it defines that an event will occur or not. The probability varies from 0 to 1.

Given that,

While taking drug, chances of experiencing nausea (n)= 24 %,

Chances of experiencing decreased sexual drive (d) = 46 %.

Also, there are 60% chances of experiencing both side effects.

Use vain diagram to solve this type of questions,

Total chances of experiencing side effects = 8 + 30 + 16 = 54

The chances of experiencing neither of the side effects = 100 - 54 = 46

So there is 46% probability of experiencing neither of the side effects.
