Answer:

x = 30

Step-by-step explanation:

Vertical angles (angles that form when 2 lines forms a cross) are equal.

The vertical angle (top left of 3x + 10 angle) of the "3x + 10" angle is the angle ADJACENT to 80 degree angle.

When we have 2 adjacent angles like this, their sum is equal to 180, so that angle would be:

180 - 80 = 100

Now, this 100 degree angle is a vertical angle to "3x+10" angle. So they are EQUAL. We can write an equation and solve for x now:

3x+10=100\\3x=100-10\\3x=90\\x=\frac{90}{3}\\x=30

Hence, x = 30

This is further explained below.

<h3>What are gridlines?</h3>

Generally, In spreadsheet software, gridlines are the light gray lines that divide the cells, rows, and columns. Gridlines are often used to maintain track of data. Gridlines are widely used in popular spreadsheet programs like Spreadsheet.

In conclusion, If the cuts can only be done along the gridlines, the cake may be divided into 20 equal pieces when cutting along the lines.

Honor Roll: Curfew 18 No Curfew 10 No Honor Roll: Curfew 2 No curfew 7
Rudik [331]

Among the students who did not make the honor roll. Then the relative frequency of having no curfew will be 7.

<h3>How to find the relative frequency?</h3>

Relative frequency is the ratio of the considered sub-group count to the total count. (so its frequency of the considered sub-group relative to the total frequency).

                                     Curfew                 No Curfew No

Honor Roll:                       18                                10

No Honor Roll:                 2                                  7

Among the students who did not make the honor roll.

Then the relative frequency of having no curfew will be 7.

Please help me with the question please ASAP ASAP please please ASAP please please help please please ASAP please please IM BEGG
Oksi-84 [34.3K]

Answer:

Ok if you look at the figure, it is a vertical angle. This means that the angle opposite to each other is congruent.

m<1 is congruent to m<3

m<2 is congruent to m<4

m<3 is 60⁰ and is congruent to m<1. This means that m<1 is 60⁰. m<4 is 30⁰ and is congruent to m<2. This means that m<2 is 30⁰.

m<1 = 60⁰

m<2 = 30⁰

m<3 = 60⁰

m<4 = 30⁰

Hope this helps, thank you :) !!
