Answer:
Step-by-step explanation:
Given that a line segment BK is an angle bisector of triangle ABC.
When the line KM intersects BC such that BM=MK
we find an isosceles triangle BMK with two sides equal
Hence by isosceles triangles theorem, two angles opposite equal sides would be equal
i.e.
The isosceles triangle theorem states that If two sides of a triangle are congruent, then angles opposite those sides are congruent.

We have
and
Solve for t in the x function
Subsitue this in for t.
We get
a square root function shifted to right 4 units and stretched vertically by a factor of 2.
We can also prove this by graphing.
Answer:
(i) Equation
(ii) 10 weeks
Step-by-step explanation:
The scenario is an equation and not an inequality , this is because the number of sit - ups Amelia planned to do is specific , which is 50 , had it been the question used the word like at least , at most 50 , it would have been an inequality.
The question is an example of Arithmetic sequence
From the statement ;
The first term = 5
The common difference = 5 ( since Amelia planned to add 5 more sit - ups to her training schedule each week )
The formula for the nth term of an Arithmetic sequence is given by :
= a + (n- 1 )d
= 50
a = 5
d = 5
n = ?
substituting the values , we have
50 = 5 + (n - 1 ) x 5
50 = 5 + 5n - 5
50 = 5n
n = 10
Therefore , it will take Amelia 10 weeks to reach her goal of 50 sit - ups
