Sally drew a circle with the right triangle prq inscribed in it, as shown below: if the measure of arc qr is 40 degrees, what is the measure of angle pqr? a) 20 degrees b) 40 degrees c) 50 degrees d) 70 degrees

D) 70 degrees

Step-by-step explanation:

Here,

Right triangle PRQ inscribed in a circle,

Let O be the centre of the circle,

If the measure of arc QR is 40 degrees,

By the central angle theorem,

,

Now, by the given options it is clear that measure of angle PQR can not 90°,

Thus, m∠PRQ = 90°,

∵ The sum of all interior angles of a triangle is supplementary,

m∠PRQ + m∠QPR + m∠PQR = 180°,

90° + 20° + m∠PQR = 180°,

110° + m∠PQR = 180°,

m∠PQR = 70°,

Hence, OPTION D would be correct.

y = 0.77(x)

step-by-step explanation:

the jacket retains this value after 23% cut or retains 77% of original value. plug original 87 jacket price for x and the remaining value should be y.
