Answer:
A. The graph has two zeroes.
Step-by-step explanation:
A <em>zero of a polynomial</em> is a value of x that makes the polynomial equal to zero.
In other words, it is <em>an x-intercept</em>.
The graph crosses the x-axis twice, so there are two zeroes.
Answer:
66.4°
Step-by-step explanation:
To find the angle XYZ, we are to use sine rule. For this, we have to first find ∠Z.
Given that: ∠X = 90° (right angle), XY = 6 cm, YZ = 15 cm. Hence:

∠X + ∠Y + ∠Z = 180° (sum of angles in a triangle)
90 + ∠Y + 23.6 = 180
113.6 + ∠Y = 180
∠Y = 180 - 113.6
∠Y = 66.4°
∠Y = ∠XYZ = 66.4°
Answer:
oc
Step-by-step explanation:
because it's oc so the side is wrong and the vertex too
