Question

The measure of ∠1 = 188 172 94

Answer 1

94

Explanation:

Answer 2

The given diagram represents a quadrilateral inside a circle .

And to find the measurement of angle 1, we have to use the following rule:

Sum of opposite angles of a cyclic quadrilateral is 180 degree.

Here one angle is 86 degree.

`\angle 1 + 86 = 180`

Subtracting 86

`\angle 1 = 180 - 86 = 94`

So the measurement of angle 1 is 94 degree.
