We are to form the combination of 6 objects taken 2 at a time. This can be expressed as 6C2
This means, there can be 15 different combinations of 2 members that can sit in the front row.
So, the answer to this question is option A
Data:
l and m are parallel lines
QR and ST are perpendicular in R
Angle 1 is 63°
The angle formed by perpendicular lines is a right angle (90°)
Angles 1 and 3 are alternate angles: angles that occur on opposite sides of a transversal line that is crossing two parallel.
Alternate angles are congruent, have the same measure.
The sum of the interior angles of a triangle is always 180°. In triangle QRT:
Use the equation above to find the measure of angle 2:
Then, the measure of angle 2 is 27°
Answer:
The answer is 8.88; You look at the number that comes after the second number (the second place after the decimal) and if that number is 5 or above then you round the second number up. (Sorry if it doesn't make sense, but that's the best I can explain it).
Step-by-step explanation:
1)
Hypotenuse2 = Perpendicular2 + Base2
c2 = a2 + b2
therefore,
c2 = (10)2 in + (24)2 in
c2 = 100 + 576
c2 = 676
c = √676
c = 26
10cm=10 * 10^-2 = 10^-1 meters
so its 2 meters + 0.1 meters = 2.1 meters
