Not really sure what you’re saying; but 5x2=10
10! = 10 * 9 * 8* 7 *6 *5 *4 *3 *2 *1 = 3628800
5! = 5*4*3*2*1 = 120
2! = 2*1 = 2
5! x 2! = 120 * 2 = 240
10! / 5!2! = 362880 / 240 = 15,120
Answer:
The other angle measures are 40 and 40 degrees respectively.
Step-by-step explanation:
100 + 2x = 180
=> 2x = 80
=> x = 40
Since it is isosceles, the two remaining sides are equal, and therefore, they will have equal angles of 40 degrees.
