Answer: x=23

Step-by-step explanation:

This is a right angle. A right angle is 90°. It already gives us 65°. So 90-65=25°. We now know (x+2) ° = 25°. 25-2=23.

We can prove this is correct by answering the problem they gave us. (23+2) is 25. 25+65=90° 90° is a right triangle which also happens to be the triangle they have shown us.

Answer:

x = 23

Step-by-step explanation:

This entire angle makes up 90° b/c of the square box

65 + x + 2 = 90

x + 67 = 90

x = 23

1. percent increase : (new number - original number) / (original number)...x 100

(22 - 20) / 20 = 2/20 = 0.1.....0.1 x 100 = 10...so there is a 10% increase

Answer:

(5,38)

Step-by-step explanation:

The correct question is

A system of equations is shown below:

y = 8x − 2

y = 9x − 7

What is the solution to the system of equations?

(−5, 38)

(−5, −38)

(5, 38)

(5, −38)

we have

$y=8x-2$ ----> equation A

$y=9x-7$ ----> equation B

Solve the system by substitution

substitute equation B in equation A

$9x-7=8x-2$

solve for x

$9x-8x=7-2$

$x=5$

Find the value of y

Substitute the value of x in the equation A or in the equation B

$y=8(5)-2=38$

therefore

The solution is the point (5,38)

$5 \sqrt{18} - \sqrt{32} \\= 5 \sqrt{9 \times 2} - \sqrt{4 \times 4 \times 2} \\ = 5 \times 3 \times \sqrt{2} - 2 \times 2 \times \sqrt{2} \\ = 15 \sqrt{2} - 4 \sqrt{2} \\ = \boxed{11 \sqrt{2} }$

<h3>11√2 is the right answer.</h3>
