10=2×5 and 14=2×7 so least common denominator will be 2×5×7=70
9/10=63/70
3/14=15/70
So 63/70-15/70=48/70=24/35

Astronomers sometimes use angle measures divided into degrees,minutes,seconds one degree is equal to 60 seconds suppose that ∠j
wel
Ok, there are two scenarios here.

1) It's a typo and "<K" should be written as "<J"

if that is the case, we can convert from degrees,minutes,seconds >> degrees like so

48 +  \frac{26}{60} +  \frac{8}{3600}

once calculated, we get 48.43 degrees.

scenario 2)

<k is the third angle in a right triangle

this would mean that <j + <K + 90 = 180

from the first example, we know that <J = 48.43 degrees

Therefor 

48.43 + <k + 90 = 180

48.43 + 90 = 138.43

so 

138.43 + <k = 180


Therefor, <K = 41.57 degrees

I really hope this helps!!:)

[-9,-4] U (-4, 19)<br><br><br> Simplify the following Union and/or intersection
Kay [80]

The union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.

<h3>What is a set?</h3>

A set is simply a  mathematical model for a collection of different things which could be elements or members.

Union of sets represented with '∪' is the combination of two sets without repetition

Intersection of sets represented with '∩' is the sum of elements common between the.

From the expression given, we have;

[-9,-4] U (-4, 19)

= { -4, -9 , 19}

[-9,-4] U (-4, 19)

= { -4}

Thus, the union and intersection of the sets is given as  { -4, -9 , 19} and { -4} respectively.
