What is angle RKL?? <br> Will you also explain how you got the answer please??
vichka [17]
The measure of angle RKL is 63 degrees.

The measure of the inscribed angle RKL times 2 is equal to the arc that it forms.

Therefore, we can write and solve the following equation:

2(-2 + 23x) = 64 + 24x - 2
-4 + 46x = 62 + 24
22x = 66
x = 3

Now, input 3 into the expression for the angle and you will have 67.
-2 + 23(3)
-2 + 69
67

Partial products are different because partial product you have 2 product when you add together gives you the answer and in regular multiplying it just straight gives you the answer without adding anything.Partial products is easier if you don't know your multiplying facts.They are similar because they both give you the same answer just using different ways of doing it
