Answer:
100+10n

100+10(10)

Answer:
No, they are not equal
Step-by-step explanation:
If x = 1
4(5+x) = 4(5+1) = 4 x 6 = 24
(5+4) + x = 9 +1 = 10
2410
2/3 of a right triangle is 60 degrees. Then x + (x+20) + 60 = 180 total.
2x + 80 = 180, so 2x = 100 and x = 50. The angles are 50, 70 and 60 (degrees)
