Answer:

The length of DE is 5 because they are similar triangle .

Explanation:

The triangles are similar. We can use the SAS similarity theorem to prove that claim.

Because the triangles are similar, the corresponding sides form a proportion like shown below

12/8 = 9/x

12x = 8*9 ... cross multiply

12x = 72

x = 72/12

x = 6 which is why the answer is choice B

Answer:

56

Step-by-step explanation:

because the triangle is 180 degrees

Answer:

x = 56°

Step-by-step explanation:

Hello!

All angles in a triangle add up to 180°

84 + 40 = 124

180 - 124 = 56°

Answer:

I think 4/10 pizza he had ate .

The amount of the pizza he ate will be 9 / 40.

Algebra is the study of graphic formulas, while logic is the interpretation among those signs.

A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.

There are ten pieces of pizza.

Anthony ate 1/8 of the pizza for dinner.

Then the amount of pizza left will be

⇒ 1 – 1/8

⇒ (8 – 1) / 8

⇒ 7/8

He ate 3/10 for a bedtime snack.

Then the amount of the pizza will be

⇒ 7/8 – 1/10

⇒ 31/40

The pizza has he eaten in all.

Then the amount of the pizza he ate will be

⇒ 1 – 31/40

⇒ 9 / 40

Then the amount of the pizza he ate will be 9 / 40.

The total number of questions is an illustration of proportions

The total number of questions is 200

From the question, we have:

Grade = 87%

Questions answered = 174

Represent the total questions with x.

So, the total question is calculated as:

174 = 87% * x

Make x the subject

x = 174/87%

Evaluate the quotient

x = 200

Hence, the total number of questions is 200

The speed of the boat will be 12.18 mph, and the angle of its direction measured from the positive x-axis will be 224.3°

First, let's define North as the positive y-axis and east as the positive x-axis.

In this coordinate axis, the angle S 60° W is equal to 210°.

Then the velocity of the boat will be:

v = (17mph*cos(210°), 17mph*sin(210°))

Now we also need to add the speed of the river, which is 6mph to the east, then the final velocity of the boat will be:

v = (17mph*cos(210°) + 6mph, 17mph*sin(210°))

v = (-8.72mph, -8.5 mph)

Then the speed of the boat will be:

|v| = √( (-8.72mph)^2 + (-8.5 mph)^2)  =12.18 mph

And the angle, measured from the positive x-axis, will be given by the arctangent of the quotient between the y-component and the x-component:

Atan(-8.5 mph/-8.72mph) = 224.3°
