Answer:
a. sine
Step-by-step explanation:
As it can be seen from the figure, triangle ABC is the right-angled triangle with Angle C is equal to 90 degree.
In a right-angled triangle, there is a formula as following:
<em>+) sine (an acute angle) = (length of its opposite side)/ hypotenuse</em>
In the figure, angle B and length of the hypotenuse are given.
As x is the length of AC and AC is the opposite side to angle B
=> So that we can use sine to find x
Tina, the youngest child = t
The middle one = t + 2
The oldest one = t + 4
Sum of all the 3 children's age is 36.
⇒t + (t + 2) + (t + 4) = 36 ←Formula to calculate Tina's age (Answer C)
t + t + 2 + t + 4 = 36
3t + 6 = 36
3t = 30
t = 10
