What is side b?

Please explain how you work it out as well

b =

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides , that is

b² + 12² = 17²

b² + 144 = 289 ( subtract 144 from both sides )

b² = 145 ( take square root of both sides )

b = ≈ 12.04 (to 2 dec. places )

b =  or  b = 12.041594...

Step-by-step explanation:

17*17 - 12*12 =    ( + = )  ( - = )  

289 - 144 =

145 =

b =    or    b = 12.041594...

i belive those are the ones that are under 90 degreese.

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
