<A = 124

Step-by-step explanation:

Remark

This figure has 7 angles. Therefore it can have 5 lines drawn from 1 vertex to all the other vertexes.  That gives you 5 triangles. See the diagram below to see the result of what I have just described. The sum total of all the interior angles is  5 * 180 = 900

Equation

Add the seven given angles from your figure to equal 900

(9x - 2) + (10x + 2) + 165 + 100 + (5x + 83) + (12x + 18) + 138 = 900

Solution

Now add all the like terms on the left together.

So this simplifies to

36x + 504 = 900                        Subtract 504 from both sides

36x + 504 - 504 = 900 - 503    Do the subtraction

36x = 396                                   Divide by 36 on both sides

x = 396/36                                  Do the division

x = 14                                          

Answer

But you want angle A.

<A = 9x - 2 = 9*14 - 2 = 126 - 2 = 124

8 2/3 is the answer

step-by-step explanation: just use a calculator

x ≥ 18 is your answer

step-by-step explanation:

let "a number" = x

(2/3)x + 17 ≥ 29

isolate the variable (x). do the opposite of pemdas (parenthesis, exponent (& root), multiplication, division, addition, subtraction).

first, subtract 17 from both sides.

(2/3)x + 17 (-17) ≥ 29 (-17)

(2/3)x ≥ 29 - 17

(2/3)x ≥ 12

next, multiply 3/2 to both sides to isolate the x

(3/2)(2/3)x ≥ 12(3/2)

x ≥ 12(3/2)

simplify. multiply, then divide

x ≥ (12 * 3)/2

x ≥ (36)/2

x ≥ 18

x ≥ 18 is your answer
