2 answers:
Answer:
A. Obtuse.
D. Isosceles.
Step-by-step explanation:
We have been given an image of a triangle. We are asked to classify our given triangle.
Upon looking at our given triangle, we can see that it has one angle that measures.
Since the measure on one angle is more than 90 degrees, therefore, our given triangle is an obtuse triangle and option A is the correct choice.
We can also see that base angles of our given triangle are equal and their opposite sides are also equal, therefore, our given triangle is an isosceles triangle and option D is the correct choice.

Answer:
Option E.
Step-by-step explanation:
Let the intended length of Rebecca's swimming is = x units
and we assume the length of the pool = l units
Now it is given in the question that " She covers one fifth of her intended distance "
That means distance covered =
" After swimming six more lengths of the pool she had covered one quarter of her intended distance"
So
x = 20×(6l)
x = 120l
Therefore, Rebecca has to complete 120 lengths of the pool.
Option E is the answer.
