Answer:
D
Step-by-step explanation:
Triangles add up do 180 degrees, and you need all of the angles to get that amount
One angle is 29 degrees, the right angle is 90, and theres a
You would then add 90 and 29 to get 119 then subtract the 119 on both sides which leaves u with a=61
From my knowledge of what an interquartile range is I have to say the answer to your question is 55.5.
Find the length of MN by setting up a ratio:
Let MN = X
X/18 = 5/6
Cross Multiply:
6x = 90
Divide both sides by 6:
x = 15
Now you know MN add it to LM for the total length of LN:
15 + 5 = 20
The ages are consecutive even numbers.
The youngest child is (x+3) years old.
Every even number is 2 more than the one before it.
So the three ages are
(x + 3), (x + 5), and (x + 7).
Their sum is x+3 + x+5 + x+7 = 3x + 15
But we're told that their sum is 42, so we can write
3x + 15 = 42 <== the equation
Subtract 15 from each side: 3x = 27
Divide each side by 3 : x = 9 <== the solution
So the three ages are 12, 14, and 16.
The oldest child is 16 years old.
