Answer:
See all the answers below.
Step-by-step explanation:
by² = d
Jay = 6
ay - cy = d.
cy - b) = y
Option A
by² = d
divide both side by b
y² = d/b
square both sides
y=√d/b
Option B
Jay = 6
Divide both sides by Ja
y= 6/Ja
Option C
ay - cy = d
y(a-c)=d
divide both sides by (a-c)
y= d/(a-c)
Option D
(cy - b) = y
y-cy=-b
y(1-c)=-b
y= -b/(1-c)
Answer:
m∠A = 30°
m∠B = 80°
m∠C = 70°
Step-by-step explanation:
By applying cosine rule in the given triangle,
b² = a² + c² - 2ac[cos(∠B)]
From the given triangle,
a = 14 m
b = 28 m
c = 24 m
(28)² = (14)² + (24)² - 2(14)(24)cos(B)
784 = 196 + 576 - 672cos(∠B)
cos(∠B) = 0.1786
∠B = 
∠B = 79.71°
∠B = 80°
By applying sine rule in the given triangle,
sinA = 0.491958
A = 29.47°
A ≈ 30°
By applying triangle sum theorem,
m∠A + m∠B + m∠C = 180°
30° + 80° + m∠C = 180°
m∠C = 70°
Step-by-step explanation:
ax2 + bx + c = 0
x12 = (-b ± √D) / 2a , D = b2 - 4ac .
5x2 + 7x + 3 = 0
a = 5 , b = 7 , c = 3
D = 49 - 60 = - 11 , x1 = (-7 - i √11) / 10
x2 = (-7 + i √11) / 10
