So here’s what i am thinking, so the right angle itself is 90°, and the top is 38°. a triangle adds up to 180° so add the 90 and 38 and then subtract it from 180. That itself gives 52°. the straight line is 180°, so you’d subtract 52° from 180° to get the outer angle, so the answer should be 128°.

Answer:

x = 128

Step-by-step explanation:

ill name the empty angle y for clarification

y + 38 + 90 = 180

y + 128 = 180

y = 52

180 - y = x

180 - 52 = x

x = 128

Determine the slope of the line that is perpendicular to the line y = -7x - 12.
Mnenie [13.5K]

Answer:

None of these answers are correct.

Step-by-step explanation:

Perpendicular lines have opposite and reciprocal slopes, which means that we take the slope and we flip it. After we've done that, we change the sign.

Since the original slope is -7, first we flip it and get -1/7. Now we change the sign and get 1/7. Therefore, the perpendicular slope of this line would be 1/7

Suppose Kalvin spins the pointer 64 times. Based on your experiment, how many times can you expect the pointer to land on 9:00,
Brrunno [24]

Answer:

16 times out of 64

Step-by-step explanation:

So, I could be wrong, but basically:

9, 10, and 11 are only 3 of the 12 possible outcomes that could happen.

3 out of 12 is 1/4.

What this means is that for every 4 times he spins the pointer, he can expect to get 9, 10, or 10 once.

Or 25% of the time

1/4 of 64 is 16.
