Question

O is the centre of the circle as shown in the figure.
If the distance between P and Q is 4 cm, then the
measure of angleROQ is

(1) 55°
(2) 35°
(3) 105°
(4) 70°

I Need The *PROPER* Steps​

Answer 1

Answer:

(4) 70

Step-by-step explanation:

POQ is diameter ( since PO =2cm=OQ )

thus POQ is a straight line.

in tri. POR

PO = OR

Thus ang.PRO = ang.OPR (angles opposite to equal sides)

then put angle sum property in this triangle

u will get ang. por = 110

as poq is a straight line ang. POR+ang. ROQ = 180

thus ang.POR+110=180

thus ang. por is 70
