- vertex: S
- sides: ST and SR
Step-by-step explanation:
The vertex is the point the rays have in common. The side rays are named by naming the vertex first, then a point on the ray.
The rays come together at point S. The name of the vertex point is S.
The sides of the angle are rays ST and SR.
Answer:
{ - 2, 1 }
Step-by-step explanation:
To determine the values let y = 0, that is
(x + 2)(2x - 2) = 0 ← in standard form
Equate each factor to zero and solve for x
x + 2 = 0 ⇒ x = - 2
2x - 2 = 0 ⇒ 2x = 2 ⇒ x = 1
The set of values are { - 2, 1 }
She has distributed the bracket incorrectly
(64 + 5) - 0.2(- 20 + 10)
= (69) - 0.2 (- 10)
=34.5 + 2
= 36.5
