Question

explain this how does this 70 came​

Answer 1

Answer:

because in near angle t two right angle is there

Step-by-step explanation:

then 90+90 =180

110-180=70

Answer 2

Answer:

as we know that sum of all the angles of a quadrilateral = 360 degrees.

given that angle poq is 110 degrees

angle OPT and angle of oqt are 90 degrees each as radius is perpendicular to tangent.

so, 110 + 90+90+ angle ptq = 360 degrees

290 + angle ptq = 360 degrees

angle ptq= 360-290 = 70 degrees

hence prove
