now, putting the similar terms together, we obtain:
this is equivalent to:
now, solving for x, we get:
then, the correct answer for the first question is:
400 minutes is the number of minutes the two plans cost the same
now, for the second question, we can replace the above value (400 minutes) into the following equation:
so that, the correct answer for the second question is:
$55 is the cost when the two plans cost the same
Answer:
Step-by-step explanation:
Given triangle ABC is a right triangle.
m∠ACB = 60°
m∠CAB = 30°
m(AC) = 1 unit
A). Shorter side of the given triangle = Side BC
By applying cosine rule,
cos(∠C) =
cos(60°) =
BC =
BC =
Length of the shorter side = 0.5 units
B). Longer side of the given triangle = side AB
By applying Pythagoras theorem in the given triangle,
AC² = AB² + BC²
1² = AB² +
1 = AB² +
AB =
AB =
AB =
Length of the longer side =
