Answer:

$\boxed{70^\circ}$

Step-by-step explanation:

Step 1. Calculate θ

$\begin{array}{rcll}70^{\circ} + \theta + 60^{\circ} & = & 180^{\circ} & \text{Angles of straight line}\\130^{^{\circ}} + \theta & = & 180^{\circ}} & \\\theta & = & 50^{\circ} & \\\end{array}$

Step 2. Calculate x

$\begin{array}{rcll}60^{\circ} + \theta + x & = & 180^{\circ} & \text{Interior angles of triangle}\\60^{\circ} + 50^{\circ} + x & = & 180^{\circ} &\\110^{^{\circ}} + x& = & 180^{\circ} & \\\\x & = & \boxed{70^\circ} & \\\end{array}$

What is the exterior and interior angle of a 18 sided polygon

GREYUIT [131]

Would assume the Polygon is an 18 sided regular polygon.

Exterior angle for regular polygon = 360/n (Sum of angles of exterior angles = 360°)

where n = number of sides.

Exterior angle = 360 / 18 = 20

Exterior angle = 20°

Sum of exterior angle + Interior angle = 180° (Both angles are on a straight line, so the sum is 180°)

Interior angle = 180° - 20°

Interior angle = <span>160°

</span>Hope this explains it.
