Answer:
Yes
Step-by-step explanation:
There is no unclosable gap. 7+1>7. 7+7>1. An isosceles triangle would be formed.
I don't see a question here, but I think your asking how many sixth graders will attend. The answer is 24.
Answer:
75%
Step-by-step explanation:
60/80 = 6/8 = 3/4 = 75%
Answer:
B. 70°
Step-by-step explanation:
If this is an equilateral triangle, then each angle is 180/3 = 60
<A = 60 = x+3x+2x
60 = 6x
60/6 = 6x/6
10 =x
Angle B will also equal 60 degrees
BDA + x + B = 180
BDA + 10 + 60 = 180
BDA + 70 = 180
BDA = 180-70
BDA = 110
BDA and y are complementary angles since they form a straight line
BDA + y = 180
110 +y =1 80
y = 180-110
y = 70
