X^2-9=0 add 9 to both sides
x^2=9 take the square root of both sides
x=±3
SinB = 8/16
sinB = 0.5
m<B = 30
answer is A. 30
Answer:
mi no hablar espanol.
Step-by-step explanation:
Answer:
m<4 = 34°
Step-by-step explanation:
m<2 = 34° (given)
m<3 + m<2 = 180° (linear pair)
m<3 + 34° = 180° (substitution)
Subtract 34° from each side
m<3 = 180° - 34°
m<3 = 146°
m<4 + m<3 = 180° (linear pair)
m<4 + 146° = 180° (substitution)
Subtract 146° from each side
m<4 = 180° - 146°
m<4 = 34°
This shows that vertical angles are congruent.
m<2 and m<4 are vertical angles formed when two straight line intersects. They are both of equal measure.
Answer: m = 3.3 mol·58.326 mol = 192 g
Step-by-step explanation: molar mass of substance is
M= (24.31+ 2·1.008 + 2·16) g/mol = 58.326 g/ mol.
Amount of substance n = m/M and mass m = n·M
