THEIR AGES

Mathematics
1 answer:
snow_tiger [21]3 years ago
6 0

Answer:

Tom’s age is 7 years

Mary’s age is 13 years

Step-by-step explanation:

Since we do not know the ages, let’s represent the ages by variables at first.

Let m represent mary’s age will t represent Tom’s age.

Now, let’s proceed to have equations.

Adding square of Tom’s age (t^2) to mary’s age give 62

t^2 + m = 62 •••••••(i)

Adding square of mary’s age (m^2) to Tom’s age give 176

m^2 + t = 176 •••••••(ii)

Now, to get the individual ages, we will need to solve both equations simultaneously.

Solving both equations simultaneously without mathematical softwares can be a little hard.

By the use of mathematical software ( wolfram alpha to be specific), we can input both equations and allow the software to solve.

By inputing these equations, we have the values of t to be 7 and m to be 13

And if we try to check by inspection, we can see that these values are actually correct.

7^2 + 13 = 62

13^2 + 7 = 176

Please help with a math problem. Please explain how you got the answer
Studentka2010 [4]

Answer:

Their sum is 140.   The measure of an exterior angle is supplementary to the respective interior angle.

Step-by-step explanation:

Since the angle are on a straight line, m2 and 140 sum to 180.

So m2=40. Because a triangle has 180 degrees, m1 and m3 must sum to 140.

The exterior angle is always on the same incline as the interior angle, so it is always supplementary to the interior angle.
