Label the 2 angles, one is x and the other is 8x.
90 = 8x + x
90 = 9x
10 =x
10 times 8 = 80. this is 8x.
10(which is x) + 80 (which is the 8x) = 90.
Step-by-step explanation:
add them by order to get the answer.
3.102+6=9.102
3/4=.75
.75+20=20.75
9.102+20.75=29.852
Answer: 29.852
White vs brown
1cup - 3cups
2cups - 6cups
3cups - 9cups
as you can see, if you add 1 to whit, you also add 3 to brown. the ratio is 1:3. every one white = 3 brown.
