Answer:
vertical angles, x=5 The angles each measure 35 degrees
Step-by-step explanation:
These are vertical angles, so they are equal
3x+20 = 10x-15
Subtract 3x from each side
3x+20-3x = 10x-13-3x
20 = 7x-15
Add 15 to each side
20+15 = 3x-15+15
35=7x
Divide by 7
35/7 = 7x/7
5 =x
The angles are equal so they each measure
3x+20 = 3(5)+20 = 15+20 = 35
The each measure 35
Answer:
Step-by-step explanation:
a straight line has the degree of 180
so you minus 125 from 180 since you already know one angle and get 55 and thats your answer
Answer:
117, 55, 54, 77, 130, 7h + 5x, 14
Step-by-step explanation:
Answer:
The number 4 is the first term of the sequence
Step-by-step explanation:
we know that
<u>Counting backwards</u> is when the numbers are count in reverse sequence
Is also know as 1 less
In this problem the sequence of counting backwards from 5 is equal to
4,3,2,1,0
therefore
The number 4 is the first term of the sequence
17,000+100+6
I think I hope I'm right
