Answer:
The measures of the angles are
, 
and 
Step-by-step explanation:
Let
x-----> one angle
y----> the smallest angle
z----> the third angle
we know that
-----> equation A
----> equation B
-----> equation C
substitute equation B and equation C in equation A and solve for y
<em>Find the measure of x</em>
<em>Find the measure of z</em>
therefore
The measures of the angles are , and
Answer:
258
Step-by-step explanation:
cause 1and 1 are the same size
So, you already know that angle CBD is 68 degrees, and the complementary angle to angle CBD is angle CBA. These angles together make 180 degrees because segment DBA is a straight line consisting of angles CBD and CBA. 180-68(the angle you already know) is 112 degrees for angle CBA. Then you repeat this process to find the other angles
The answer is b cause none of x is the same number
We have 1 green and 8 non-green.
We get a probability of 8/9 of a non-green for the first marble and a probably of 7/8 for the second being non green, so
p = (8/9)*(7/8) = 7/9
Answer: 7/9
