I am just completely lost and am unsure of how to approach this problem.
Anastasy [175]

Answer:

68°

Step-by-step explanation:

As BA⊥BD, so ∠ABD = 90°

also, ∠ABD = ∠CBD + ∠ABC

⇒ 90° = 4x + 52° + 8x - 10°

⇒  12x = 48°

⇒  x = 4°

now,

∠CBD = 4x + 52°

          = 4(4°) + 52°

          = 68°

LekaFEV [45]

Answer:

Question 2: Option B

Step-by-step explanation:

The number of ounces and the total price for yogurt cup A is not stated, therefore, I can not answer question 1 properly.

<h3>For question 2:</h3><h3 />

Unit rate formula for price is: \frac{price}{quantity}

32 ounces of yogurt sell for 1.62.

So:

\frac{1.62}{32} =0.050625

0.050625 ≈ 0.05

<em>Option B should be the best answer. </em>
