Can anyone help me?
goldfiish [28.3K]

Given:

A right angle triangle ABC, right angled at C.

To find:

The measure of θ.

Solution:

In a right angle triangle,

\tan \theta=\dfrac{Opposite}{Adjacent}

In triangle ABC,

\tan \theta=\dfrac{AC}{BC}

\tan \theta=\dfrac{2.7}{5}

\tan \theta=0.54

It can be written as

\theta=\tan^{-1}0.54

\theta\approx 28.369

Therefore, the measure of θ is 28.369.

First we will go to the section that lists that students that like hotdogs.  76 students out of 150 like hotdogs.  Out of those 76 students, which of them like burgers?  
32 students like hotdogs and burgers.  32/76 is equal to .421..., which when multiplied by 100 is equal to approximately 42.1%.  We found the conditional frequency, or the column frequency.  The correct answer is C.

Since y is anything greater than 2, you would draw a straight line across the point (from left to right) and if you had to shade you would shade above it (:
