To solve #8, we need to make ∠CBD equal to ∠DBE in an equation and solve for x. Then we will plug x into the expression for ∠A.

∠CBD = ∠DBE

(x + 10) = 60

  • Subtract 10 from both sides.

x = 50

  • Plug x into ∠A (x + 5).

(50) + 5 = 55

  • The measure of ∠A = 55°.
<h3>55° is your answer.</h3>

There are three kinds of rock: igneous, sedimentary, and metamorphic.
Igneous rocks form when molten rock (magma or lava) cools and solidifies. Sedimentary rocks originate when particles settle out of water or air, or by precipitation of minerals from water. They accumulate in layers. Metamorphic rocks result when existing rocks are changed by heat, pressure, or reactive fluids, such as hot, mineral-laden water. Most rocks are made of minerals containing silicon and oxygen, the most abundant elements in the Earth’s crust.
