Atangent-tangent angle intercepts two arcs that measure 149° and 211
what is the measure of the tangent-tangent angle?

31°

Step-by-step explanation:

A tangent-tangent angle is the angle formed by two tangents to a circle (angle BCD in attached diagram).

Lines CB and CD are tangent to the circle, then angles ABC and ADC are right angles (with 90° measure).

Angle BCD  intercepts two arcs that measure 149° and 211°, this means minor arc BD has the measure of 149° and major arc BD has the measure of 211°. If  minor arc BD has the measure of 149°, then angle BAD has the measure 149° too.

The sum of all measures of interior angles of quadrilateral is always 360°, then

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
