Simplify the expression:
10s2+5–10s2

Prove that 16^4-2^13-4^5 is divisible by 11.

Match the following reasons with the statements given to create the proof. 1. do = ob, ao = oc sas 2. doc = aob given 3. triangle cod congruent to triangle aob vertical angles are equal. 4. 1 = 2, ab = dc if two sides = and ||, then a parallelogram. 5. ab||dc if alternate interior angles =, then lines parallel. 6. abcd is a parallelogram cpcte

Which angle has the same measure as the dehedral angle formed by the orange face and the purple rectangle
