Answer:

x = 25

Step-by-step explanation:

Looking at the triangle we know that it is a right triangleor a 90⁰ triangle.

(2x + 15)⁰ + x⁰ = 90⁰

2x + 15⁰ + x⁰ = 90⁰

2x + x + 15⁰ = 90⁰

3x + 15⁰ = 90⁰

3x + 15⁰ - 15⁰ = 90⁰ - 15⁰

3x = 75⁰

3x / 3 = 75⁰ / 3

x = 25⁰

Now plug the x value in the missing angles.

2x + 15⁰

2(25⁰) + 15⁰

50⁰ + 15⁰

65⁰

According to the sum of triangle, all angles add up to 180⁰. Even though this is a right triangle, it should add up 180⁰ in order to be a triangle.

65⁰ + 25⁰ + 90⁰ = 180⁰

Hope this helps and stay safe, happy, and healthy, thank you :) !!

Scorpion4ik [409]

Answer:

Step-by-step explanation:

4x+3y=-24

eq. of any line perpendicular to given line is

3x-4y=a

4y=3x-a

y=3/4x -a/4

where a is an arbitrary constant.

How do i solve for (2x/5)+1=13/5

NNADVOKAT [17]

Answer:

x = 4

Step-by-step explanation:

$\frac{2x}{5} +1 = \frac{13}{5}$
$\frac{2x+5}{5} = \frac{13}{5}$ divide both sides by 5
2x + 5 = 13 subtract 5 from both sides
2x = 8 divide both sides by 2
x = 4

Solve for x. Leave your answer in simplest radical form.

maks197457 [2]

Step-by-step explanation:

step 1. let's call the line in the middle y.

step 2. y = sqrt(5^2 + 7^2) = sqrt(74). pythagorean theorem.

step 3. x^2 + y^2 =100 (pythagorean theorem))

step 4. x^2 + (sqrt(74))^2 = 100.

step 5. x^2 = 100 - 74

step 6. x^2 = 26

step 7. x = sqrt(26). note: sqrt is the square root.

Which of the following is equivalent to log408 rounded to three decimal places?

il63 [147K]

The answer is: $0.564$

The explanation is shown below:

1. To solve this problem you must apply the following proccedure:

2. You have the logarithm expression:

$log40(8)=x$

3. First, you must apply the following property:

$a^{loga(x)} =x$

4. Therefore, you have:

$40^{log40(8)}=40^{x} \\ 8=40^{x}$

5. By applying logarithm on both sides, you have:

$log(8)=log(40^{x} )$

6. By applying the property $log(a)^{b} =blog(a)$ :

$log(8)=xlog(40)$

7. Solve for x:

$x=log(8)/log(40)\\ x=0.564$
