Answer:
h = 5.4
Step-by-step explanation:
Basically these are 2 similar triangles. That means:
Corresponding sides are proportional.
We can set up a ratio of each triangle separately and equate, cross multiply and solve for "h".
h corresponds to 2.4
2.9 corresponds to 1.3
Setting up the ratio and solving for h:

Rounded to 1 decimal place,
h = 5.4
Step-by-step explanation:
Length of arc of a circle is given as:

Thus, the measure of central angle is 140°.
Each pair of interior angle and the exterior angle
So the exterior angle = 360° - the interior angle.
