Step2247 [10]

Answer:

$B= 41$ ; $C = 56$ ; $A = 83$

Step-by-step explanation:

Given

$A = 2x + 1$

$B = x$

$C = x + 15$

Required

Arrange the angles from smallest to largest

First, we need to determine the value of x.

Since, it is a triangle:

$A + B + C = 180$

Substitute values for A, B and C

$2x + 1+ x + x + 15 = 180$

Collect Like Terms

$2x + x + x = 180 - 15 -1$

$4x = 164$

Solve for x

$x= 164/4$

$x= 41$

Solve for A, B and C

$A = 2x + 1$

$A = 2 * 41 + 1$

$A = 82 + 1$

$A = 83$

$B = x$

$B= 41$

$C = x + 15$

$C = 41 + 15$

$C = 56$

From Smallest to Largest, we have:

$B= 41$ ; $C = 56$ ; $A = 83$

Find the mean of this set of numbers.

mezya [45]

This is how you find the mean of a number:

To find the mean of a number, you need to add up all the numbers listed (so, 5, -11, 7, 12, -1 and 0) and then divide it by the amount of numbers there are listed. 5 + -11 + 7 + 12 + -1 + 0 equals 12, and since there are 6 numbers you then divide 12 by 6. 12 divided 6 is 2.

So the answer is A. I hope this helped you!
