Answer:
Step-by-step explanation:
This triangle is a 30°-60°-90° triangle, so you should always remember the rule shown in the picture. Because y is across from the 60° angle, it will be . 3 is x because it is across from the 30° angle, so y will be .
Answer:
I have not been able to answer it sorry
It would be about 270
40 + 40 is 80 so take half of the hits he would get and add it to the number of hits in total then times it by 10
T) -7x+10y=20. M) -3x+y=-2 - ,
2(8x-5y)=35(2) -1(x+y)=-6(-)
-7x+10y=20. -3x+y=-2
16x-10y=70. -x-y=6
9x=90. -4x=4
[x=10] [x= -1]
-7(10)+10y=20. -3(-1)+y=-2
-70+10y=20. 3+y=-2
10y=90. [y= -5]
[y=9]
6c + 8a - 200 = 1000 ....or could be 6c + 8a = 1200
if no kids came...only adults..
6(0) + 8a = 1200
8a = 1200/8
a = 150 <== 150 adults would have to attend
