Answer:
x=11
Step-by-step explanation:
34(RT) minus 12(RS)=22. 22 divided by 2 equals 11.
The probability of drawing a green marble is 8/20.
there are 20 marbles total and 8 of them are green.
5 to the 7th power times 5 to the 6th power
Since these are supplementary angles (two angles which sum to 180°) we can say:
4x+x=180 combine like terms on left side
5x=180 divide both sides by 5
x=36°
