Answer:
opt. B
Step-by-step explanation:
g=60 because equilateral triangle ang=60
<KMN=120 because of linear pair
<h= 180-(120+29)= 31
g+h= 60+31= 91
Answer:
to be honest i think it would be c
Step-by-step explanation:
Perfect squares are n² where n is a whole number
whole numbers are like 0,1,2,3,4,5,6, etc
no decimal or fractions
we can do that be looking at the perfect squares we know
2²=4
3²=9
4²=16
5²=25
6²=36
7²=49
8²=64
etc
so we see 47 is between 6² and 7²
therefor, for n²=47, n is between 6 and 7 and is therfore not a whole number
that makes 47 not a perfect square
Answer:
30 Degrees
