x = 81 degrees (The sum of a triangle's angles must be 180 degrees. 48 + 51 = 99, and 180 - 99 = 81)
y = 99 degrees (Y and X are on a supplementary angle. Like a triangle, a supplementary angle's angles must add up to 180 degrees. 180 - 81 = 99)
z = 129 degrees (Z and the 51 degree angle are also on a vertical angle. 180 - 51 = 129)
Hope this helps!
Answer:
the answer B
...................................
This question is not even trying to test your arithmetic. It's just testing
to see whether you know how to read numbers in words properly.
When you read numbers in words, the only time you ever say "and"
is for a decimal point. There are no decimals in this question, so the
"and" is not a part of any numbers.
The question gives you two numbers. The word "and" is the marker
that's
BETWEEN them. The two numbers are 1,300 and 950 .
The first thing the question wants you to do is write the numerical
expression for all the words. That's (1300 - 950) / 4 .
The next thing you're supposed to do is"evaluate the expression" ...
find out what number it all boils down to. I don't think you'll have
any trouble with that now.
Answer:
the answer of this question will be 0.2
