So here we go, lines OA and OB are radii of the circle O
since the measurement of ∡ O is given it is easy to find the other measurements.
180-85 = 95° (all the sides of a triangle = 180°)
That angle divided by two
$\frac{95}{2}$ = 47.5°
We know that the radii are the sides which makes that triangle isosceles.
So m∡BAC = 47.5°
Answer is B)47.5

alexdok [17]

Answer:

Step-by-step explanation:

A 5x8 matrix $A$ represents a linear transformation between the vector space $\mathbb{R}^8$ and $\mathbb{R}^5$ . Remeber that the columns of $A$ generate the image of the linear transformation, which is a vector subspace of $\mathbb{R}^5$ . Therefore, $\dim \text{Col}A \leq 5$ , which is the dimension of the the total space.

Choice C is the best answer because the singular pronoun “that” agrees in number with its singular antecedent “transition.”

According to the statement

Here we have to find the correct word which replaces the given words in the comics gold to silver.

So, For this purpose, we know that the

In the comics Gold into silver: "The reverse alchemy" we have to replace the word those.

And

Choices A and B are incorrect because the plural pronouns “those” and “these” do not agree with the singular antecedent “transition.” Additionally, choice B is incorrect because “these” implies that whatever is being referred to is at hand, not in the past. Choice D is incorrect because a pronoun is needed to complete the comparison of transitions between comic book ages.

So, Choice C is the best answer because the singular pronoun “that” agrees in number with its singular antecedent “transition.”
