The remaining side using cosine theorem is:
BC ^ 2 = 36 ^ 2 + 36 ^ 2 - 2 * 36 * 36 * cos (65)
BC = root (1496.573466)
BC = 38.68557181
Then, for the area we have:
A = root (s (s-a) * (s-b) * (s-c))
s = (a + b + c) / 2
Substituting:
s = (36 + 36 + 38.68557181) / 2
s = 55.34278591
A = root (55.34278591 * (55.34278591-36) * (55.34278591-36) * (55.34278591-38.68557181))
A = 587.2874463
Rounding off we have:
A = 587.3
Answer:
A = 587.3
Answer:
x = - 8 and (- 8, 0 )
Step-by-step explanation:
Given a quadratic in standard form
y = ax² + bx + c ( a ≠ 0 )
Then the equation of the axis of symmetry which is also the x- coordinate of the vertex is
x = - 
y = x² + 16x + 64 ← is in standard form, with
a = 1 and b = 16, then
x = -
= - 8
Equation of axis of symmetry is x = - 8
Substitute x = - 8 into the quadratic and evaluate for y
y = (- 8)² + 16(- 8) + 64 = 64 - 128 + 64 = 0
vertex = (- 8, 0 )
