Answer is A
Answer:
as discriminant = 9, it has two real solutions.
Step-by-step explanation:
for eqn ax^2 + bx + c, discriminant = b^2 - 4ac
y = 4x^2 - 5x + 1
discriminant = (-5)^2 - 4(4)(1)
= 25 - 16
= 9
as discriminant > 0, it has two real solutions.
Step-by-step explanation:
angle b = 71°
so, x + b = 180° ( linear pair )
x + 71° = 180°
x = 180° - 71°
x = 109°
Now, a + y = 180° ( <em>linear</em><em> </em><em>pair </em><em>)</em>
93° + y = 180°
y = 180° - 93°
y = 87°
<em>Hence</em><em>,</em><em> </em><em>the </em><em>value</em><em> of</em><em> x</em><em> </em><em>is </em><em>1</em><em>0</em><em>9</em><em>°</em><em> </em><em>and </em><em>y </em><em>is </em><em>8</em><em>7</em><em>°</em><em>.</em>
