Answer:
14.3
Step-by-step explanation:
9/5= 9.2/x (cross multiply)
5 x 9.2= 46
46 ÷ 9 = 5.1
9.2 + 5.1 = 14.3
Answer:
x = 21°
Step-by-step explanation:
Vertical angles have the same measures, therefore:
3x - 30 = 2x - 9
x - 30 = -9
x = 21°

Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = - 
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = -
= - 1
Equation of axis of symmetry is x = - 1
