Write 45 in the form k squareroot 5 where k is an integer

This question is impossible.

Step-by-step explanation:

Explanation:

I got this question on a practice maths paper, and it has to be a mistake.

The previous answer posted here says that 45 = 9√5, which is clearly wrong:

We know that 45 = 9 x 5 but this person has said 45 = 9 x √5, and clearly 5 √5.

To add, the mark scheme of the practice paper I did said that the answer was 3√5 which is also wrong.

I think the question meant to ask "Write √45 in the form k√5 where k is an integer" in which case the answer 3√5 would be correct:

√45 = √9 x √5

√9 = 3

Therefore, √45 = 3√5

I hope this answers your question!

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
