I'm not too sure but i think:
A
_ r = x
Y
Answer:
x₁ = √15
x₂ = - √15
Step-by-step explanation:
x² - 15 = 0
x² = 15
x = ±√15
x₁ = √15
x₂ = - √15
Answer:
m∠BCA = 43°
Step-by-step explanation:
ABCD is a kite having m∠BAD = 46° and m∠ABC = 114°
∠BAD and ∠BCA are the vertex angles of the kite.
Since, diagonal of kite bisect the vertex angles
m∠BAC = m∠DAC = 
m∠BAC = 23°
By applying triangle sum theorem in ΔABC,
m∠ABC + m∠BCA + m∠BAC = 180°
114° + m∠BCA + 23° = 180°
m∠BCA = 180° - (114° + 23°)
= 43°
