3. x: 180-99 = 81º (angles on a straight line equals 180)

y: 115-81 = 34º (exterior angle is sum of opposite interior angles)

4. y: 180-64 = 116 (angles on a straight line equals 180)

x: 126º

two steps

angles on straight line equals 180: 180-118 = 62º

exterior angle is sum of opposite interior angles: 62+64 = 126º

sorry if i misread any of the numbers, let me know if i did and i'll fix it

Eddi Din [679]

Answer:

6.30$

Step-by-step explanation:

If you add 7.80$ and 7.80$ that come to 4 hot dogs,

The rest of the money is how much one soda cost ( 2.40$ ),

Dividing that 7.80$ by 2, To only have one hot dog, would put you at

3.90$ fro one hot dog, then all you have to do is add them together, to get the total of 6.30

 7.80   |     17.00      |    7.80/2  |    2.40

+ 7.80  |    - 15.60     |    3.90     |  + 3.90

15.60   |   2.40          |                |   6.30

Fill in the blank.
Amiraneli [1.4K]

Answer: x ≈ 18 ft

Step-by-step explanation:

We will use our trig knowledge to solve this.

The man is standing 10 ft away, but we also need to add the 5 ft shadow as well as that is a point on our triangle.

We can set up a simple trig equation of: tan(50) = x/15

x being the height of the lamppost.

Now we solve.

tan(50) = 1.1918

1.1918 *15 = x

x = 17.876

Now round to the nearest foot.

x ≈ 18 ft
