Answer:
x = 19
Step-by-step explanation:
Solve for x:
3 x + 43 = 100
Subtract 43 from both sides:
3 x + (43 - 43) = 100 - 43
43 - 43 = 0:
3 x = 100 - 43
100 - 43 = 57:
3 x = 57
Divide both sides of 3 x = 57 by 3:
(3 x)/3 = 57/3
3/3 = 1:
x = 57/3
The gcd of 57 and 3 is 3, so 57/3 = (3×19)/(3×1) = 3/3×19 = 19:
Answer: x = 19

Step-by-step explanation:
Answer:
Step-by-step explanation:
Triangle WXY is a right angle triangle.
From the given right angle triangle,
XW represents the hypotenuse of the right angle triangle.
With ∠W as the reference angle,
WY represents the adjacent side of the right angle triangle.
XY represents the opposite side of the right angle triangle.
To determine XY, we would apply the Sine trigonometric ratio. It is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 59 = XY/7
XY = 7 Sin59 = 7 × 0.8572
XY = 6
