The sum of interior angles of a triangle is 180 degrees. If we’re trying to find the triangles last angle on the right, we will subtract 180-60-50 which equals 70. The angle missing on the right side is 70 degrees. There are opposite angles in this shape so the other angle beside a would also be 70 degrees. Now we only have a left and you do the same thing with the sum of interior angles with that triangle. So you do 180-70-65 and you’re left with 45. Therefore, a is 45 degrees.
Step-by-step explanation:
20 x 399 x 5
= (20×5) × 399
= 100×399
= 39,900
Seventy two(72), eighty six(86)
Answer:
no, it is not the answer is(2,-2)
Answer:
is neither significantly low nor significantly high.
Step-by-step explanation:
From the information given, we know that:
The mean is 
and the standard deviation is 
.
The range rule of thumb says that:
Applying these definitions, we get that
We note that is between 
and 
, which indicates is neither significantly low nor significantly high.
