Yes
The rule to check if a triplet of numbers can represent the sides of a triangle is the following: the sum of the length of two sides must exceed the third one.
This happens for all possible couples in your case:
Answer:
a,d,e
Step-by-step explanation:
75+a1 = 180
so a1=105
a1=x-15
105=x-15
x=120
then using rules of parallel lines with commone intersecting line gives the others.
Total number of marbles : 12
amount of blue marbles : 4
4/12 = 1/3 or 33%
the probability of choosing a blue marble 1/3 or 33%
Answer:
<h2>
x = 60°</h2><h2>
y = 60°</h2>
Step-by-step explanation:
it looks like an isosceles triangle, but is an equilateral triangle, 3 equal sides and 3 equal angles, you have the value of 120°, and the interior angle is 60° (180 - 120 = 60°), this angle is equal to angle y.
y = 60*
the sum of the interior angles of a triangle is 180°
180 - 60 - 60 = 60°
x = 60°
