Answer:
It is an octogan and it isn't regular, you are correct.
Step-by-step explanation:
Normal octagons look like a stop sign. This one looks like a star.
Answer:
yes

Answer:
b. and d.
Step-by-step explanation:

Answer:
m<1 =95
m<2 = 130
Step-by-step explanation:
I take it you want the size of <1 and <2?
<ABC + 95 = 180 Same straight line.
<ABC = 180 - 95 Subtract 95 from both sides.
<ABC = 85 Combine
===========================
<1 + <ABC = 180 Interior angles on the same side of the transversal = 180
<1 + 85 = 180
<1 = 180 - 85
<1 = 95
=============================
Givens
<ABC = 85
m< 1 = 95
<ADC = 50 Given
m<2 = ?
m<2 + <ABC + m<1 + 50 = 360 The four angles of a quadrilateral add to 360
m<2 + 85 + 95 + 50 = 360
m<2 + 230 = 360
m<2 = 360 - 230
m<2 = 130
Sample space is 36C4
Now, we want to know all of the combinations that have 1 digit in it.
So, we can have one here:
1XXX
X1XX
XX1X
XXX1
But we have 10 different digits to choose from. So, we need to introduce the combination term, nCr, where n is a list of all digits and r is how many we want.
Since we only want one, we will need 10C1 for the number of digits. But we need to choose three lowercases, so it becomes 10C1 × 26C3
Since it's a probability question, we need to divide that by our sample space, 36C4, and our percentage becomes 44%
