The given triangle is a right triangle.
The tangent of an angle of right triangle is obtained by dividing the opposite side of the angle with the adjacent side of the angle.
The opposite side of angle R is 5 cm and the adjacent side of angle R is 12 cm.
tan R = 5 / 12 = 0.4167
R = arctan (0.4167) = 22.6 degrees.
The median thickness of the entire glacier is calculated with the arranging the given dimensions of the thickness from least to highest.
29, 34, 35, 36, 38, 40, 41, 43, 44, 46
The middle tern is the 5th and 6th terms which are equal to 38 and 40. Average of this cool is still 39.
Answer:
Step-by-step explanation:
If you are solving for the equation 2x + 19 = 0, the steps are as follows.
2x+19=0
2x = - 19 (Move the 19 over to the other side)
x = - 9 1/2 (divide both sides by 2 to get x by itself.)
-x(3x-10)=8
-3x^2+10x=8 (DISTRIBUTE)
-3x^2+10x-8=0 (BALANCE TO ZERO)
(-3x+4)(x-2)=0 (FACTOR)
(-x+4/3)(x-2)=0 (SIMPLIFY)
{x=2 OR x= 4/3}
