Addition is the correct answer.

x^2 is the part where you get the second degree term. If you add x^2+x^2 you get 2x^2. If you subtract x^2-x^2 you get 0. If you multiply x^2*x^2 you get x^4, which is a fourth degree term

Find x<br><br> May I please receive help?
NikAS [45]

Answer:

x = 63°

Step-by-step explanation:

See the attachment

The measure of the angles in a triangle = 180 .  If the sides of a triangle are congruent, then the base angles are equal.  So in the triangle with the 72°, you have another angles = 72°.  Looking at the same triangle, 72° + 72° + part of the right angle = 180°. Do the math!  72° + 72° = 140°; 180° -144° = 36° (this is the measure of the piece of the right angle that is in the triangle with the 72° angle..   So the other part of the 90°(right angle) = 90° - 36° = 54°.

Now to solve for x:  You know that if the sides are congruent in a triangle, then the base angles are equal. Thus this triangle angles are x, x, and 54°.

You know that a triangle = 180°, so x + x + 54° = 180°; 2x +54° = 180°;           2x = 126°; x = 63°

Which relationship describes angles 1 and 2?
Grace [21]

Sounds like your describing complementary angles (a pair of angles that add up to be 90 degrees) but not super sure based on that description you have there.
