Answer:
Step-by-step explanation:
Given:
< C = 53°
< B = 80°
a = 2
Required:
Find b
Solution:
The question given suggests we are given measures for a ∆.
To find side b, which corresponds to angle B, first, we'd find angle A, which corresponds to side a, then apply the Law of sines to find side b.
=> A = 180 - (53 + 80) = 47°
Law of Sines:
Plug in the values into the formula
Cross multiply
Divide both sides by sin(47) to make b the subject of formula
(nearest tenth)
23 because if u add bothe of them up
<em>The discriminant must be zero.</em>
Step-by-step explanation:
A Perfect-Square Trinomial is given by the form:
The discriminant in the quadratic formula is:
So in order to get a perfect square,<em> the discriminant must be zero.</em>
