What is the answer to this question ?

Drupady [299]

If there is a really short way of doing this, I don't see it. The only way I know to do it is to find the third angle of both triangles.

So for F the third angle for each of the pairs is
left side: 180 - (51 + 30) = 180 - 81 = 99
right side: 180 - (109 + 30) = 180 - 139 = 41
This is not the answer.

G
180 - (92 + 70) = 180 - 162 = 18
180 - (28 + 70) = 180 - 98 = 82
This is not the answer either.

H
180- (58 + 30) = 180 - (88) = 92
180 - (90 + 58) = 180 - 148 = 32
Not at all.

180 - (35 + 82) = 180 - 117 = 63
180 - (82 + 63) = 180 - 145 = 35
This pair has a third angle that is equal to the other triangle's pair. This is your answer.

5.Find the slope of a line perpendicular to

Lemur [1.5K]

Hi there!

When the slopes of two perpendicular lines are multiplied the outcome will be -1.

The slope is the number that is positioned in front of the variable x in the formula. In this case the slope of the given line is -2/5.

Let's call the slope of the perpendicular line m and take into account the given data of the question and my earlier explanation. We then find the following:

$- \frac{2}{5} \times m = - 1$
Divide both sides by - 2/5.

$m = \frac{ - 1}{ - \frac{2}{5} } = 2 \frac{1}{2} = \frac{5}{2}$
The answer is B.

~ Hope this helps you!

lyudmila [28]

<span>Part A:

The price of the tv when purchased online is given by

$160\left( \frac{100+30}{100} \right)=160\left(\frac{130}{100}\right) \\ \\ =160(1.3)=\$208$

Part B:

T</span><span>he price of the tv when purchased at the superstore is given by:

</span><span> $160\left( \frac{100+40}{100} \right)=160\left(\frac{140}{100}\right) \\ \\ =160(1.4)=\$224$

Part C:

T</span><span>he difference between the prices is given by $224 - $208 = 16

For every 10% increase in the markup, the prices increases by $16.
