Answer: second option.

Step-by-step explanation:

When two parallel lines are intersected by a third line (which is called "Transversal"), the angles that are of the same side of the transversal (but one located in interior and the other one located in the exterior), are known as "Corresponding angles".

Corresponding angles are congruent.

You can observe that the angle 2 and the angle 6 are Corresponding angles. Therefore, the missing justification is: "Corresponding angles formed by a transversal on parallel lines are congruent."

HELPPPP PLZZ ND THANK YOU SOO MUCH

Answer:

50, 40, 30, 250, 350

Step-by-step explanation:

1/2 = 0.5, 0.5 x 100 = 50 (0.5 -> 5 -> 50)

2/5 = 0.4 (10 / 5 [the denominator] = 2, 0.2 x 2 [the numerator] = 0.4), 0.4 x 100 = 40 (0.4 -> 4 -> 40)

3/10 = (10 / 10 [the denominator] = 1, 0.1 x 3 [the numerator] = 0.3), 0.3 x 100 = 30 (0.3 -> 3 -> 30)

5/2 = 2.5 (2 1/2), 2.5 x 100 = 250 (2.5 -> 25 -> 250)

7/2 = 3.5 (3 1/2), 3.5 x 100 = 350 (3.5 -> 35 -> 350)

Note: I'm not sure if I understand the question completely, but I changed the fraction into a decimal and multiplied it by 100. Not sure what it means by "Divide fraction".

GIVING 100 POINTS!!! An observer (O) is located 900 feet from a building (B). The observer notices a helicopter (H) flying at a

slamgirl [31]

Answer:

1035.33 feet

Step-by-step explanation:

OBH is a triangle and the sum of the angles of a triangle = 180

∠OBH = 90°

∠OHB = 180 -(49 + 90) = 41°

The law of sines that the ratio of each side of a triangle to the sin of the angle opposite it is the same

Thus

A/sinα = B/sinβ = C/sinγ

where A, B and C are the three sides of the triangle and α, β, γ corresponding respectively to the angles opposite them.

Using the law of sines

$\frac{OB}{sin 41} = \frac{BH}{sin49}$

Therefore BH which is the height the helicopter is flying at is

$BH = OB \frac{sin49}{sin41}$

≈ 1035.33 feet

Dani is training for a marathon. Her target speed is 25 miles per hour. She currently runs 15 miles in 1/2 an hour. Does she ach

marissa [1.9K]

Answer:

target speed for the marathon has been achieved and exceeded

Step-by-step explanation:

Given that :

Target speed = 25 mph

Current speed = 15 miles in 1/2 an hour

Current speed :

15 miles in 0.5 hours

X miles in 1 hour

0.5x = 15 miles

X = 15 / 0.5

X = 30 miles per hour

Hence, current speed in miles per hour = 30mph

This means that her target speed for the marathon has been achieved and exceeded
