Say you have 3 cakes. How many cakes would you have eaten if you ate 1/3 of the three cakes? One, you have eaten one cake, out of the three you have.

How many cakes do you have left if you eat 2/3 of the three cakes? Two, you have eaten 2 cakes, and have 1 cake left.

It is a similar approach here, except the confusing part is working "forward", when you really have to work "backward". If you have driven 30 miles, and you have driven 2 parts out of the trip when there is 3 parts of the trip, how many miles have you driven? Hint: Dividing 30 by 2 gives you what fraction of the distance to Jeff's grandmother?

Answer:

83 m  (nearest metre)

Step-by-step explanation:

This can be modeled as a <u>right triangle</u>, where the base is 60 m and the height is the height of the building.

<u>Alternate Interior Angles Theorem (Z-angles)</u>

If a line intersects a set of parallel lines in the same plane at two distinct points, the alternate interior angles that are formed are congruent.

Using the Alternate Interior Angles theorem, the angle between the ground and the dashed line (angle of elevation) is 54°.

<u>Tan trigonometric ratio</u>

\sf \tan(\theta)=\dfrac{O}{A}

where:

  • \theta is the angle
  • O is the side opposite the angle
  • A is the side adjacent the angle

Given:

  • \theta = 54°
  • O = height of building (h)
  • A = 60

Substituting the given values into the formula and solving for h:

\implies \sf \tan(54^{\circ})=\dfrac{h}{60}

\implies \sf h=60 \tan(54^{\circ})

\implies \sf h=82.58291523...

\implies \sf h=83\:\:m\:(nearest\:metre)

Answer:

(3x + 12) + (2x - 38) + (x + 10) = 180 \degree \\ 6x - 16 = 180 \\ 6x = 196 \\ x = 32.6 \\(3x + 12)  : =  > 110 \degree \\ (2x - 38) :  =  > 27.3 \degree \\ (x + 10) :  =  > 42.6 \degree

What is the measure in degrees of &lt;ABC?
babunello [35]
Those two angles total equal 180 degrees. 
Since we know the first angle equals 155 degrees.
180-155+25.
ABC is 25 degrees.
