Answer:
16
Step-by-step explanation:
The equation is X2 – 19x + 48 = 0
Using the quadratic formula
X= - b +- √ ( b^2 - 4ac)/ 2a
Where a= 1 b= -19 c= 48
Substitute into the formula we have

Answer:
x = 19 cm
Step-by-step explanation:
perimeter = 46 = 2(x + 4)
2x + 8 = 46
2x = 38
x = 19
Answer:
y = 110°
Step-by-step explanation:
The inscribed angle CHF is half the measure of its intercepted arc CDF
The 3 arcs in the circle = 360°, thus
arc CDF = 360° - 160° - 60° = 140°, so
∠ CHF = 0.5 × 140° = 70°
∠ CHF and ∠ y are adjacent angles and supplementary, thus
y = 180° - 70° = 110°
