Answer:

Value of x is 60°.

Step-by-step explanation:

According to the theorum,

The exterior angle is equal to the sum of the opposite two interior angles.

Exterior angle is 144°. The interior angles are 84° and x°

\longrightarrow x° + 84° = 144°

\longrightarrow x° = 144° - 84°

\longrightarrow x° = 60°

Value of x is 60°.

180° < x < 270°, what is the value of tan-1(0.577)?
Allisa [31]
Think:  "Find <span>tan-1(0.577)" means "Find the ANGLE in Quadrant III whose tangent is 0.577.  Because the angle is in QIII, both the opp side and the adj side are negative.  Here you have four answer choices.  The correct answer MUST be within the interval 180 and 270 degrees.  Only one of the given answer choices satisfies that criterion.  Which one is it?

What is in scientific notation?
suter [353]

So for this, you will be dividing 9.3/3.1 and 10^34/10^17 separately.

Starting with 9.3/3.1, that equals 3

Now with 10^34/10^17, remember that the rule with dividing exponents with the same base is that you are just subtracting the exponents. In this case: 10^(34 - 17) = 10^17

Now we put the two quantities together, and your answer will be 3 x 10^17, or the second option.
