Find the value of x
see picture

x = 14

Step-by-step explanation:

As shown on the diagram: m∠STU = 8x , m∠RST = 7x - 54

m∠STU + m∠STR = 180

∴ m∠STR = 180 - m∠STU = 180 - 8x

RS ≅ST  ⇒ m∠STR = m∠SRT = 180 - 8x

∠STU is exterior angle at U

∴ m∠STU = m∠RST + m∠SRT

∴ 8x = (7x - 54) + (180 - 8x)

Solve for x:

∴ 8x = 7x - 54 + 180 - 8x

∴ 8x = 126 - x

∴ 9x = 126

∴ x = 126/9 = 14

So, the value of x = 14

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
