In circle a shown below, segment bd is a diameter and the measure of arc cb is 36°: points b, c, d lie on circle a; line segment bd is the diameter of circle a; measure of arc cb is 36 degrees. what is the measure of ∠dbc?

The measure of ∠DBC is 72°.

Step-by-step explanation:

Given information: BD is a diameter, A is center of circle, Arc CB=36°.

According the angled inscribed in a semicircle theorem, the angle inscribed in a semicircle is a right angle.

According to the central angle theorem, the angle inscribed on the circle is half of its central angle.

By angle sum property, the sum of interior angles of a triangle is 180 degrees.

Therefore the measure of ∠DBC is 72°.

answer: the sun

explanation:

water cycle describes the evaporation of water from earth's surface, formation of clouds and precipitation water back onto the surface of earth. seventy percent of the earth is covered with water in the form of seas and oceans. the heat of the sun causes the evaporation of water from the surface of the ocean. the water vapors rise and condense to form water droplets. the collection of these water droplets form clouds which rain down again.

the evaporation of the oceans surface water as part of the water cycle is caused by the sun
