Hello!

∠E and the angle measuring 119 degrees (we'll refer to this as ∠A) can be classified as supplementary angles. Supplementary angles are two angles whose measures add to a sum of 180 degrees (a straight line). Therefore, we can conclude that sum of ∠E and ∠A is 180 degrees. We can use this information to create the following equation:

∠E + 119 = 180

Now subtract 119 from both sides of the equation:

∠E = 61

We have now proven that ∠E is equal to 61 degrees.

I hope this helps!

<span>Angles on one side of a straight line always add to <span>180°.

Therefore:
e + 119° = 180° |subtract 119° from both sides
e = 61°

Other:
e = c = 61°
d = 119°</span></span>

Since 6 is in the hundredths place,

96/100

You can divide that by two for a different, but equal fraction.

48/50, 24/25

24/25 is the simplest form.

I hope this helped you!

A 50-foot flagpole is at the entrance of a building that is 300 feet tall. If the length of the flagpole's shadow is 30 feet at

Soloha48 [4]

The equation you can use to solve the problem is;

50/30 = 300/x

Next Cross Multiply

50x = 9000

x = 9000/50

x = 180

The building's shadow is 180 feet tall
