Answer 1

`\Large \boxed{\sf 42}`

Explanation:

Apply tangent secant exterior angle measure theorem

If a tangent and a secant intersect in the exterior of a circle, then the measure of the angle formed is 1/2 the difference of the measures of its intercepted arcs.

`\displaystyle (1)/(2) *(136-52)=42`

Answer 2

x = 42

Explanation:

The angle between the tangent and the secant is

`(1)/(2)` difference of the measure of the intercepted arcs, that is

x = 0.5( 136 - 52) = 0.5 × 84 = 42
