The no. of letters in the world (MATH) = 4
the no. of favourable outcomes = 10
hence‚ probability of getting the letters (MATH) 2/5
A
x=y^2-9
x+9=y^2
square root both sides
+-sqrt(x+9)
Answer:
x = 11
Step-by-step explanation:
ΔLKM is an equilateral because a triangle with all 3 sides that are congruent is an equilateral triangle.
Angles in an equilateral triangle are all 60°.
Thus, ∠L = 60°.
=> 3x + 27 = 60
=> 3x = 33
=> x = 11
C=3.14 x 26
C=81.64
C=2(3.14 x 13)
C=81.64
