Find the measure of an exterior angle of each regular polygon: 100-gon.

If this is a 100-gon, then not only does it have 100 sides, it also has 100 central angles. Each one measures 360/100 = 3.6. This is the vertex angle for each of those 100 triangles. 180 - 3.6 = 176.4, which has to be split equally between the 2 base angles. This puts each of those at 88.2. If you are looking for the exterior angle to each of those, it's the supplement of them. 180-88.2 = 91.8

Find the unknown angle measures

Usimov [2.4K]

Answer:

Step-by-step explanation:

ok so this is a vetical angle. so they are equal to 180. so if 1 measurement is found the other is the difference of 180 and that angle measeurement.

so y is the same as 110

and 180 - 110 is 70, so x and z are equal to 70.

i hope this helped you :)

On Thursday, the amount of snowfall was 1/8 cm. On Wednesday, the amount of snowfall was 4 1/4 cm. What was the amount of snowfa

marysya [2.9K]

The total amount of snowfall on the two days combined is 4 3/8 cm

<h3>Addition of fractions </h3>

From the question, we are to determine the amount of snowfall on the two days combined

From the given information,

the amount of snowfall was 1/8 cm on Thursday

The amount of snowfall was 4 1/4 cm on Wednesday

Then,

The total amount of snowfall on the two days combined will be

$\frac{1}{8}+4\frac{1}{4}$ cm

= $\frac{1}{8}+\frac{17}{4}$

= $\frac{1+34}{8}$

= $\frac{35}{8}$

= $4\frac{3}{8} \ cm$

Hence, the total amount of snowfall on the two days combined is 4 3/8 cm
