What is the value of a?
O5 units
O5 1/3 units
O6 2/3 units
O7 units

The value of a is  ⇒ 2nd answer

Step-by-step explanation:

Let as revise the Pythagoras Theorem

In the right triangle ABC, where ∠B is a right angle (AC is the hypotenuse, Ab and BC are the legs of the right angle)

(AC)² = (AB)² + (BC)²

(AB)² = (AC)² - (BC)²

(BC)² = (AC)² - (AB)²

If BD is drawn perpendicular to AC, we can use these rules

(AB)² = AD × AC

(BC)² = CD × AC

(BD)² = AD × CD

AB × BC = BD × AC

Step-by-step explanation:

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

wow ok so the answer is 1k or just k

because of combining like terms xd
