Ding ding, I'm here again! ΔABC is an isosceles right triangle. Use the isosceles triangle base angles theorem and the sum of the interior angles of a triangle to determine the measures of ∠ACB and ∠ABC.

A: ∠ACB = 90° and ∠ABC = 45°

B: ∠ACB = 45° and ∠ABC = 90°

C: ∠ACB = 90° and ∠ABC = 90°

D: ∠ACB = 45° and ∠ABC = 45°

Which age groups shows the graestest diferrence between males and females

One disadvantage that darwin faces today is w. enemy attacks x. natural disasters y. lack of land bridge z. high population density

15 points need quick 1. looking at your graph and the geologic time scale during what period did this rock form? what is the age span of the rock, in millions of years? 2. this rock sample is limestone and shale. with what you know about rock formation, what type of environment did these organisms live in? 3. if some of these fossil samples were found in a rock also containing leaf fossils, could you use radiocarbon dating to determine the age of this rock? explain.
