Answer:

<u>The correct answer is B.  145 in²</u>

Step-by-step explanation:

Let's recall that formula of the surface area of a pyramid:

S.A. = 1/2*(4 * side of the base * height) + side of the base ²

Replacing with the values provided, we have:

S.A. = 1/2*(4 * 5 * 12) + 5²

S.A. = 1/2 * 240 + 25

<u>S.A. = 145 in²</u>

Please Help. Will give brainliest.
Keith_Richards [23]

Answer:

<em>mDBC = 341 °</em>

Step-by-step explanation:

Arc DBC is almost the whole circle, if you were to exclude the degree measure of minor arc DC; which is, in other words m∠ DPC

Now by Vertical Angles Theorem:

m ∠ DPC = m∠ APB, ⇒ provided BD, and AC are diameters

m∠ DPC = 19°

This would mean ⇒

mDBC = 360 - m∠ DPC,

mDBC = 360 - 19,

mDBC = 341 degrees ( ° )
