Do the side lengths 15,20 and 25 form a right triangle?<br><br><br> PLEASEEEE HELPPPP!!! asap
sveticcg [70]
<h3>Answer: Yes, those sides form a right triangle</h3>

===================================================

Work Shown:

a^2+b^2 = c^2

15^2+20^2 = 25^2

225+400 = 625

625 = 625

Since the last equation is true, this makes the first equation true for those a,b,c values. Therefore, by the pythagorean theorem converse, this is a right triangle.

Side note: c is always the longest side.

There are 2 more angles. m angle 7 and m angle 8
Licemer1 [7]
ANSWER:

A and B aren't parallel lines, as the alternate angles aren't equivalent to each other.

For m angle 1 -

Vertically opposite angles are equivalent to each other.

m angle 1 is vertically opposite m angle 4.

Therefore:

m angle 4 = 100

m angle 1 = m angle 4

m angle 1 = 100

For m angle 6 -

Co-interior angles add up to 180°.

m angle 4 and m angle 6 are co-interior angles.

Therefore:

m angle 4 = 100

m angle 4 + m angle 6 = 180

100 + m angle 6 = 180

m angle 6 = 180 - 100

m angle 6 = 80

For m angle 7 -

Vertically opposite angles are equivalent to each other.

m angle 6 is vertically opposite m angle 7.

Therefore:

m angle 6 = 80

m angle 7 = m angle 6

m angle 7 = 80

For m angle 8 -

Corresponding angles are equivalent to each other.

m angle 8 and m angle 4 are corresponding angles.

Therefore:

m angle 4 = 100

m angle 8 = m angle 4

m angle 8 = 100

Hence, the angles are as follows:

m angle 1 = 100

m angle 6 = 80

m angle 7 = 80

m angle 8 = 100

The total cost f(x), in dollars, for renting a vacation house for x days is shown:
MA_775_DIABLO [31]

Answer:

Option D.The number of dollars it costs to rent the house for 10 days

Step-by-step explanation:

we have

f(x) -----> the total cost for renting a vacation house

x ------> the number of days rented

we know that

f(x)=10+250x

so

For x=10 days

substitute in the function

f(10)=10+250(10)=$2,510

f(10) represent the number of dollars it costs to rent the house for 10 days

Mark tossed six balls while playing a number game. Three ball landed in one section, and three balls landed in another section.
luda_lava [24]
Mark's score could be 120,000. Each ball would be worth 20,000 points and since 2,000 times 6 is 120,000, that's how many points he could have.
