BM=CM implies that BCM is isosceles. This means that an altitude from the third vertex A of the triangle ABC, which must necessarily go through M will intersect BC exactly in the middle. This implies that the angles <CBA = <BCA which means the ABC is isosceles.

Answer:
7 1/2 cups
Step-by-step explanation:
First, convert the measure of ice cream from pints to cups:
1 pint = 2 cups
⇒ 4 pints = 4 × 2 = 8 cups
Therefore,
Milkshake = 8 cups of ice cream + 1 1/2 cups of milk
= 9 1/2 cups
If he drinks 2 cups of milkshake:
Remaining milkshake = 9 1/2 - 2
= 7 1/2 cups
Answer: A
Step-by-step explanation:
Looking at the conditions, we can eliminate D. An isosceles triangle has 2 equal sides. 2 cm, 3 cm, 4 cm don't have 2 equal lengths.
We can next eliminate C. C is a right scalene triangle. Even if this is a scalene triangle, the key is the work "right". Any right triangle, regardless of it's angles, always fit the Pythagorean Theorem. C does not fit the Pythagorean Theorem.
2²+3²=4²
4+9=16
13≠16
We are left with the options A and B. A and B can both be correct answers, but it is the condition given in the problem that makes A the right answer. A states acute scalene triangle. That means there is at least 1 acute angle. Technically, B is also correct, but because the problem explicitly states 29°, that makes A the correct answer.
