The Measures Of The Angles Of A Triangle Are Shown In The Figure Below. Solve For X.(3x+13)(8x+14)109

Answers

Answer 1
(3x + 13) + (8x + 14) + 109 = 180°

(3x + 13) + (8x + 14) = 71°

11x + 27 = 71°

11x = 44°

x = 4
Answer 2

Answer:

x = 4

(3x + 13) = 25°

(8x+ 14) = 46°

Step-by-step explanation:

(3x + 13) + (8x +14) + 109 = 180 (Angles of a triangle)

11x + 136 = 180

11x = 180 - 136

11x = 44

x = 4

Substituting the value of x

(3x + 13) = 3×4 + 13 = 12 + 13 = 25

(8x + 14) = 8×4 + 14 = 32 + 14 = 46

Which values are solutions of the inequality 7>z-4? Choose all that apply? Options:
6 7 10 11 20. I READY MATH

Answers

7>z-4
7 + 4> z-4 + 4
11 > z
z < 11

Possible values of x are 6, 7 and 10.

Solutions of the inequality are 6, 7 and 10.

What is inequality?

An inequality is a relation which makes a non-equal comparison between two numbers or other mathematical expressions. It is used most often to compare two numbers on the number line by their size.

Given inequality

7 > z - 4

If x = 6; x - 4 = 2 < 7

x = 7; 7 - 4 = 3 < 7

x = 10; 10 - 4= 6 < 7

x = 11; 11 - 7 = 7 not less than or equal to 7

Thus, possible values of x are 6, 7 and 10.

We need to do 90-61, which is 29. X = 29, because the base of 61 and the right of the x is equal to a right angle.

Answer:

x=29 degrees

Step-by-step explanation:

Both angles shown ad up to a 90 degree angle. We can see this because on the adjacent side there is a box indicating that it is a right angle. The three angles add up to 180, thus if we subtract 90 degrees due to the angle on the left of the y axis, the angles on the right of the y axis must add up to 90 as well.

Since the angles on the right must add up to 90, we set an equation to solve for x:

61+x=90(subtract 61)

x=29 degrees
