Answer:

Here,

x+2+3x+6 = 180 [ Sum of opposite angle of cyclic quadrilateral is Supplementary ]
4x + 8 = 180
4x = 180 - 8
x = 172/4
x = 43

Now,

Angle A = 3 * 43 + 6
= 129 + 6
= 135

Lena estimated the height of a desk to be 38 inches. The actual height is 41 inches.

Leno4ka [110]

Answer:

7.3%

Step-by-step explanation:

First you have to find out what 38 out of 41 is as a percentage

This is 92.68%

so now we have to do

100.00 - 92.68 this is 7.32

But you said round to the nearest tenth so it would actually be rounded down to 7.3%

An 8-pound bag of tomatoes costs $5.60. At the same rate, what would be the cost of 11 pounds of tomatoes?

Evgesh-ka [11]

Here is the solution to the given problem above.
Given that for an 8 pound bag of tomatoes costs $5.60, we would want to know how much will it be for 11 pounds. First, we should know how much does it cost per pound. So 5.60 divided by 8 is 0.7. So per pound of tomatoes costs $0.7. Now to know how much for 11 pounds, we multiply 0.7 by 11 and we get $7.70. The correct answer therefore would be option C. $7.70. Hope this answer helps.

“The sum of 6 consecutive integers is 519” what is the third number in this sequence?

Rashid [163]

Let x be the first integer, then
:
x + (x+1) + (x+2) + (x+3) + (x+4) + (x+5) = 519
:
6x + 15 = 519
:
6x = 504
:
x = 84
:
*****************************
Our sequence is
:
84, 85, 86, 87, 88, 89
:
The third integer is 86

Find the value of x. Round your answer to the nearest tenth.

Fantom [35]

Hello again! So we will be using the pythagorean theorem ( $leg^2+leg^2=hypotenuse^2$ ) to solve for the bottom leg of the triangles. After we do that, we'll subtract the value of the legs from 31, and that'll be x.

Plug in 17 and z (or any variable that isn't x) into the leg variable and 19 into the hypotenuse variable, and from there we can solve.

$17^2+z^2=19^2$

Solve the exponents to get $289+z^2=361$

Subtract 289 on each side to get $z^2=72$

Lastly, square root each side of the equation and your answer should be $z= \sqrt{72}$ (To get more accurate answers, you shouldn't round until the end of the problem)

Nextly, we will need to subtract $\sqrt{72}$ from 31. And since there are 2 triangles, you'll need to multiply $\sqrt{72}$ by 2.

$x=31- \sqrt{72} *2 \\ x=14.0$

In short, x = 14.0
