Ответ:
x=65
Step-by-step explanation:
First, we need to find the 2 base angles of the triangle
105 is adjacent to another angle, and they are on a straight line. Therefore they are supplementary and add to 180 degrees
105+z=180
Subtract 105 from both sides
z=75
140 is adjacent to another angle, and they are on a straight line. Therefore they are supplementary and add to 180 degrees
140+y=180
Subtract 140 from both sides
y=40
Now, we know the two base angles of the triangle are 40 and 75. The angles in a triangle add to 180 degrees, so
40+75+x=180
Combine like terms by adding 40 and 75
115+x=180
Subtract 115 from both sides
x=65
Ответ:
A) both have the same spread
Step-by-step explanation:
Find the similarityas you can see the pattern of o and x is the same meaning.
for o its starts at 10
10 - o
20- o o
30 - x
40- o o o x x
50- o
60- x x x
70 - x
i shall show the spread comparison
For o10 20 30 40 50
o oo ooo o
for x30 40 50 60 70
x xx xxx x
this shows they have the same spread
the correct answer is A) both have the same spread
