In Euclidean geometry, the angles of a triangle add to 180, which means the remaining angle has a measure of 86 degrees.
In spherical geometry, it's impossible to know the measure of the remaining angle precisely without knowing any more info about the triangle. The sum of the interior angles is between 180 and 540 degrees, so the missing angle is somewhere between 87 and 445 degrees.
Answer:
N=22.815≈23
Step-by-step explanation:
SIN N=19/49
N=\sin^{-1}(\frac{19}{49})
N=sin
N=22.815≈23
Area of all triangles : 10 x 12 = 120 120 divided by 2 = 60 then, 60 x 4 = 240
Area of the Square: 12 x 12 = 144
Surface Area of the Pyramid: 240 + 144 = 384 square millimeters!!
Hope This helps :)
Vicki is correct!
That is because they all took 2/6
so simplified they all took 1/3
Hope this helps ;)
Answer:
1/8
Step-by-step explanation:
Leonard spent 1 fourth of his money on a sandwich.
Fraction of money spent on sandwich = 1/4
He spent 2 times as much on a gift for his brother as on some comic books.
= 1/4 × 2
= 2/8
Hence, Fraction of money spent on Comic books = 2/8
He had 3 over 8 of his money left.
Let us represent his total money has: 1
The fraction of his money that he spent on the comic books is calculated as:
= 1 -( 1/4 + 2/8+ 3/8)
Lowest Common Denominator = 8
= 1 - (2 +2 + 3/8)
= 1- 7/8
= 1/8
Therefore, the fraction of his money that he spent on the comic books is 1/8
