Answer:

No triangles are possible.

Step-by-step explanation:

<u>Given</u>:

m∠A = 18°
side c = 19 in
side a = 4 in

In a triangle ABC:

A, B and C are the interior angles.
a, b and c are the sides opposite the corresponding interior angles.

The interior angles of a triangle <u>sum to 180°</u>.

Given m∠A = 18°, the sum of angles B and C is:

⇒ m∠B + m∠C = 180° - 18° = 162°

As there is no answer option where the sum of angles B and C equals 162°, no triangles are possible from the given answer options.

Evaluate 8-2.<br>A. -16<br>B. -64<br>C. -1/64<br>D. 1/64<br>

makvit [3.9K]

I'm assuming you meant to write 8^(-2) or $8^{-2}$ where the -2 is the exponent over the 8.

If my assumption is correct, then we use the rule $a^{-b} = \frac{1}{a^b}$

So,

$a^{-b} = \frac{1}{a^b}\\\\8^{-2} = \frac{1}{8^2}\\\\8^{-2} = \frac{1}{64}$
