Yes because think of it like this. Put a imagenary 1 in front of y and either it will still be the same

Yes, he is correct. Any value multiplied by one is equal to the original value. Ex: 4x1=4. So, the same applies with y: yx1y=y.

Answer:

A = 75°

B = 90°

C = 15°

Step-by-step explanation:

The diagram tells us that C = 15°.

The diagram places a square in the angle of B, showing you the angle is a 90° right angle.

You can solve for A because all angles of a triangle must equal 180°. 180° - 90° (B) = 90°. 90° - 15° (C) = 75°, the measure of A.

Answer:

yes it is possible to have a triangle with 8.8 cm, 8.0 cm and 8.8 cm.

Step-by-step explanation:

Condition on sides of triangle:

The triangle inequality states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.
It is not possible to have sum to be less than the length of the third side.
A triangle with three given positive side lengths exists if and only if those side lengths satisfy the given condition
Let a, b and c be three sides of triangle.

$a + b > c\\a+c>b\\b+c>a$
