Which angles are supplementary to each other?

Mathematics
1 answer:
Sav [38]3 years ago
8 0

Answer:

∠9 and ∠12

Step-by-step explanation:

Supplementary angles are two angles that add up to 180. Looking at all the answer choices, A, C, and D have either Big-Big angle or Small-Small angle. What we need is Big-Small angle that is next to eachother, which is ∠9 and ∠12.

Hope this helped.

WARRIOR [948]

Using the probability concept, the distribution is given as follows:

  • P(X = 0) = 0.1.
  • P(X = 1) = 0.15.
  • P(X = 2) = 0.55.
  • P(X = 3) = 0.15.
  • P(X = 4) = 0.05.

<h3>What is a probability?</h3>

A probability is given by the <u>number of desired outcomes divided by the number of total outcomes</u>.

The distribution gives the <u>probability of each outcome</u>.

In this problem, there were 60 trials, hence the distribution is given as follows:

  • P(X = 0) = 6/60 = 1/10 = 0.1.
  • P(X = 1) = 9/60 = 3/20 = 0.15.
  • P(X = 2) = 33/60 = 11/20 = 0.55.
  • P(X = 3) = 9/60 = 3/20 = 0.15.
  • P(X = 4) = 3/60 = 1/20 = 0.05.

Can someone please answer and EXPLAIN ILL MARK BRAINLIEST
12345 [234]

Answer:

adjust city gallons to 3 gallons and freeway to 7 gallons

make your line in the chart:

3   |  10-3 = 7   |   3(25) = 75   |   7(40) = 280   |   75 =280 =355   |   355   |   yes

Step-by-step explanation:

x = city gallons

y = freeway gallons

x+y = 10        then y = 10-x

25x+40y = 355

substitute for y

25x+40(10-x) = 355

25x+400-40x = 355

-15x+400 = 355

subtract 400 from each side

-15x = -45

divide both sides by -15

-15x/-15 = -45/-15

x = 3 gallons

y = 7 gallons

Which measurement could create more than one triangle? A.? A triangle with sides measuring 5 inches, 7 inches, 9 inches B. A tri
rewona [7]

Answer: B. A triangle with sides measuring 50 mm 35 mm and a non-included angle measuring 25° .

Step-by-step explanation:

A. A triangle with sides measuring 5 inches, 7 inches, 9 inches

Only one triangle can be possible because all the triangles with equal sides must be equal by SSS congruence rule.

B. A triangle with sides measuring 50 mm ,35 mm and a non-included angle measuring 25°.

More than one triangle can be possible because there is no congruence rule for two equal sides and one non-equal angle ( no SSA rule exist).

C. A triangle with sides measuring 5 cm, 10 cm, and 15 cm .

This triangle is not possible because it doesn't satisfy triangle's inequality as 5+10=15  [Triangles inequality : a+b> c, where a, b, c are sides of triangle]

D. A triangle with sides measuring 8 cm and 12 cm in an included angle measuring 85°.

Only one triangle can be possible because all the triangles have two equal sides and their included angle is equal by SAS congruence rule.

Hence, the required measurement to create more than one triangle:

A triangle with sides measuring 50 mm 35 mm and a non-included angle measuring 25° .

So, correct option is B.
