Answer:

x=31

Step-by-step explanation:

Complementary angles are angles that add up to 90 degrees.

So, 2x+28=90.

To solve:

1. Subtract 28 from both sides

2x=90-28

2x=62

2. Divide both sides by 2

x=62/2

x=31

Answer:

so ABD is equal to 90 degrees. all you have to do is subtract angle CBD (which is 38 degrees) from angle ABD (which is 90 degrees). this would mean that 2x = 52. you then solve for x which means x = 26.

Step-by-step explanation:

90 - 38 = 52

2x = 52

x = 26

andrezito [222]

Answer:

The ladder is 28.6 feet long.

Step-by-step explanation:

Given that:

Length of base = 17 feet

Length above the ground = 23 feet

These forms two legs of right angled triangle.

The length of ladder will be the hypotenuse.

Using Pythagorean theorem;

$a^2+b^2=c^2\\(17)^2 + (23)^2 = c^2 \\289 + 529 = c^2 \\c^2 = 818$

Taking square root on both sides

$\sqrt{c^2}=\sqrt{818}\\c=28.6$

Hence,

The ladder is 28.6 feet long.

Inessa [10]

Answer:

Step-by-step explanation:

You can look at the photo for more information:

Use the pythagorean theorem to solve this problem

$height^{2} = slant height^{2} - half of base diagonal^{2}$

= $92.8^{2} -19.8^{2}$

= 8219.8

Then square root it, we have: $\sqrt{8219.8}$ = 90.66

So the height is: 90.66

Robert is incorrect: Surface are of A is 30 + 30 + 42 + 42 + 35 + 35 = 214 square centimeters. Surface area of B is 120 + 120 + 168 + 168 + 140 + 140 = 856 square centimeters. B's surface area is 4 times as great as A's.
