What is the measure of angle 1?

Mathematics
1 answer:
ioda3 years ago
6 0

Answer:

see explanation

Step-by-step explanation:

∠1 and 170° form a straight angle and are supplementary, thus

∠1 = 180° - 170° = 10°

∠1 and ∠3 are vertical angles and congruent , thus

∠3 = 10°

∠2, 15° and ∠3 form a straight angle and sum to 180°, thus

∠2 = 180° - 15° - 10° = 155°

Thus

∠1 = 10°, ∠2 = 155°, ∠3 = 10°

Answer:

5

Step-by-step explanation:

Let's first find the slope of the linear function represented by the table:

As we move from x = 4 to x = 6 *an increase of 2), y increases by 6 from -2 to +4.  Thus, the slope of this line is m = rise / run = m = 6/2, or 3.

Now we compare the two slopes:  -2 and 3.

The postive difference between them is 5.  This is Answer B.

What is the slope of the line that passes through the points(-5,-9) and (-5,-13)? Write your answer in simplest form.
Valentin [98]

Answer:

slope is undefined

ex. a straight vertical line like x = 2 would have an undefined slope

Step-by-step explanation:

formula is

y2-y1 / x2-x1

-13 + 9 / -5 + 5

-4 / 0

slope is undefined

straight vertical line like x = 2 would have an undefined slope

undefined slope is the slope of any vertical line that goes up or down. There is no horizontal movement and hence the denominator is zero while calculating the slope. Thus the slope of the line is undefined.

Answer:

x=0.6241

Step-by-step explanation:

Square both sides and end up with

75.24+x=75.8641

isolate x

x=75.8641 - 75.24

x=0.6241
