Answer:
1) Correct
2) Wrong
3) Operate Within Parentheses
4) 60°
Step-by-step explanation:
The original equation is correct because 180 - (60 + 60) = 180 - 120.
180 - 120 = 60
If Puzzled Penguin operated within the parentheses first he would have arrived at the correct answer.
Hope this helped.
Answer:
Step-by-step explanation:
First note that the triangles shown are isosceles triangles due to equality of two of their sides which is radius. So their baseline angles are equal
Since their middle angle are equal too, so their 3 angles are the same. It menas both triangles are similar.
However, we know two of three sides are equal, but the third should be also because of their similarity.
y+4 = 2y - 3
2y - y = 4 - 3
y = 4+3
y = 7
Therefore,
2y-3 = 2.7-3 = 14-3 = 11
Answer is 11 centimeters
Number of faces + (Number of vertices - Number of edges) = 2
So plugging in the numbers it would then be
18+(12-30)=2
18-18=2
0=2
Kelvin would be wrong and I disagree with him. (Because ...*plugin work cited above*)
4/10 because 10-6 is 4 :)
Answer:
13824
Step-by-step explanation:
