Answer:
A
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
let x be the measure of the congruent angles, then
x + x + 100 = 180, that is
2x + 100 = 180 ( subtract 100 from both sides )
2x = 80 ( divide both sides by 2 )
x = 40
Thus the measure of one of the congruent angles is 40°
Answer:144
Step-by-step explanation: a coin has 2 possibilities so 2 coins have 2x2 = 4 possibilities. A normal six-sided dice has 6x6 = 36 possibilities. 4 x 36 = 144 (this might be wrong)
Ok, this is a pretty easy answer. 23 times 630 is 14490. You get this answer by searching it up on a calculator or actually doing it by paper.
