How do we know the angle of 45 degrees is always equal to the square root of 2 over 2?

The question is not correct, you mean the the sine and cosine of 45 degrees is always square root 2 over 2. 

Well you need to know how the sine and cosine are calculated. I would search in google for "sine and cosine in a unit circle". There is a very good Khan academy video that explains this in 10 minutes. Watch and learn :-)

your friend claims that two isosceles triangles ABC and DEF are congruent if two corresponding sides are congruent. he explains
Svetach [21]
Think about the fact that you can have two types of isosceles triangle: one of them that is a right triangle (isosceles right triangle) such as a 45-45-90 triangle and the other type can be just a regular triangle that has two sides that are congruent but it isn't a right triangle. 

Thus, you would need more info about the triangles in order to conclude that the two isosceles triangles are congruent to each other.

3 consecutive integers for 273
a_sh-v [17]

Answer:

90, 91 and 92

Step-by-step explanation:

Given

Consecutive integers = 273

Required

Find the integers

The question seem to be incomplete. However, I'll assume we're dealing with sum.

Let the smallest integer be y.

So,

y + y + 1 + y + 2 = 273

Collect like terms.

y + y + y = 273 - 2 - 1

3y = 270

Divide both sides by 3

y = 90

Hence, the integers are 90, 91 and 92
