Age of tom=t
age of john=j
age of andy=a
t<a
if j is not older than t, then he is less than or equal to t so
j ≤ t
but there is an oldest so therefor we assume that j < t
t < a
j < t
subsitute
j<t<a
andy is oldest
tom is second
john is youngest
Answer:
We know that the angles of a triangle always add up to 180 degrees, and we also know that this triangle is congruent because it has the two dashes on the side of the triangle. We also know that x is 90 degrees but this is not drawn to scale but we can just assume it is 90 degrees.
We can tackle the triangle on the right first subtracting 47 and 90 from 180 which will give us the angle y as angle DAC is congruent to angle BAC.
180-47-90=43.
We also know that angle x is 90 degrees already or at least we assume so but to further prove our point we know that angle BCA is congruent to angle CBA which makes angle CBA 47 degrees, so subtracting 43 and 47 from 180 we have 90 degrees.
Therefore y is 43 degrees and x is 90 degrees.
it's kinda confusing ngl
*assuming that x is a right angle

Answer:
By breaking it up in shapes
Step-by-step explanation:
I annotated your photo and it's attached below :) that's an example on how to break shapes into easier parts. So yeah
One minute as a decimal part of an hour is 0.01666667
To find this I divided 1 by60
