Answer:

Positive.

Step-by-step explanation:

When you see two negative signs directly next to each other (as shown in the given expression), it will become a positive sign:

7 - (-4) = 7 + 4 = 11

Positive is your answer.

* To be fair, even if there is only one negative sign, the answer will still be positive, however, I am assuming you are suggesting only the sign, and not the answer.

Two angles are supplementary. The measure of one angle is 4 times the measure of the other angle. What is the measure of the sma

ANSWER

The smaller angle is

$y = 36 \degree$

.EXPLANATION

Let the angles be
$x \: and \: \: y$

where y is the smaller angle.
Since they are supplementary, they will add up to 180°.

This implies that,

$x + y = 180 \degree...(1)$

If one angle is 4 times the other, we can then write the following equation,

$x = 4y...(2)$

We put equation (2) into equation (1) to get,

$4y + y = 180 \degree$

$5y = 180 \degree$

We divide through by 5 to obtain,

$y = 36 \degree$

This implies that,

$x = 4(36)$

$x = 144 \degree$
