( B) ∠OSN is the correct answer.
As we know two angles are Supplementary if sum of that two angles is 180° or they form a linear pair
The meaning of linear pair is that the two angles should be such that the non common arms should lie on opposite side of the common arm and at the point of intersection of two angles have the same vertex. Also the two non common arms should form a line.
SO IF ONE ∠ IS Ф° OTHER SHOULD BE 180-Ф°. FOR EXAMPLE ON ∠ IS 60° OTHER WILL BE 180-60°=120°
Supplement of
1.45°=135°
2.70°=110°
Answer:
B
Step-by-step explanation:
minimum = 1
first quartile = 12
median = 6
third quartile = 16
maximum = 19
1. (x² + 24) factors as the difference of two squares (x² - (-24)) where -24 is the square of the complex number i√24 = 2i√6. The factoring is
(x - 2i√6)(x + 2i√6)
2. The square of half the coefficient of the x-term needs to be added: 4.5² = 20.25
This number goes in both boxes.
3. This is the square of (y² +20), so the factorization is similar to that for problem 1.
y⁴ + 40y² + 400 = (y² + 20)² = (y -2i√5)²(y +2i√5)²
An acute angle is <90 degrees
a right angle is equal to 90 degrees
an obtuse angle is >90 degrees
Any triangle has angles adding to 180 degrees
therefore three acute angles, eg. 60, 60 and 60 degrees can make up a triangle
2 acute angles and a right angle, say 45 and 45 degrees and 90 degrees make a triangle
any obtuse angle + a right angle will be larger than 180 degrees, so no triangle can exist. another acute angle will make the number of degrees even larger
any 2 obtuse angles will make a number larger than 180 degrees, so with an acute angle is impossible
2 acute and an obtuse angle is possible, say 40, 40 and 100 degrees
