What's the ratio equivalent to 15 to 60.

The answer to the question is 1:4

Step-by-Step explanation:

We have to divide each number over here by the LCF of 15.

The LCF (Least Common Factor) of 15 is 5.

Given the LCF of 15 is 15, we will divide both given numbers by 15.

We will put the numbers back in order from least to greatest.

The ratio we find is 1:4, and the answer to your question is 1:4.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

δabc ≅ δdcb by sas because

db ≅ ac . . given (side)

bc ≅ bc . . reflexive property (side)

∠dbc ≅ ∠ acb . . alternate interior angles where transversal bc crosses parallel lines bd and ac (included angle)
