60 degrees

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.

So if you add 40 + 90 + x = 180

You get 130 + x = 180

If you subtract 180 - 130

You get 60.

ale4655 [162]

Answer:

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles

Step-by-step explanation:

Given as :

The total distance cover by Lana , Tony , Mark = 484 miles

Let The distance drove by Lana = L miles

The distance drove by Tony = T

The distance cover by Mark = M

So , L + T + M = 484 miles

Now, The distance of Tony = $\frac{1}{3}$ of Lana distance

Or, T = $\frac{1}{3}$ × L

And The distance of Mark = 15 + The distance of Lana

Or, M = 15 + L

Now.

L + $\frac{1}{3}$ × L + 15 + L = 484

Or, 2 L + $\frac{L}{3}$ = 484 - 15

Or, 2 L + $\frac{L}{3}$ = 469

Or, $\frac{7 L}{3}$ = 469

Or, 7 L = 469 × 3

∴ L = $\frac{1407}{7}$

I.e L = 201

The distance drive by Lana = 201 miles

The distance drive by Mark = 15 + L =15 + 201 = 216 miles

The distance drive by Tony = $\frac{1}{3}$ × 201 = 67 miles

Hence The distance drive by each person is

The distance drive by Lana = 201 miles

The distance drive by Mark = 216 miles

The distance drive by Tony = 67 miles Answer

The value of x in the given diagram is 10

<h3>Similar triangles </h3>

From the question, we are to determine the value of the side labeled x

First, we will find the value of side |BC|

By the <em>Pythagorean theorem</em>, we can write that

|BC|² = 12² + 16²

|BC|² = 144 + 256

|BC|² = 400

|BC| = √400

|BC| = 20

Now,

Since ΔABC and ΔDEF are similar, we can write that

|BC| / |EF| = P ΔABC / P ΔDEF

But,

P ΔABC = 12 + 16 + 20 = 48

Thus,

|BC| / |EF| = P ΔABC / P ΔDEF becomes

20/ |EF| = 48/24

20/x = 2

x = 20/2

x = 10

Hence, the value of x in the given diagram is 10
