Its 2/3 because after finding the lcd you find its the same number in the question
Answer:
I believe the answer to be 387.11
Step-by-step explanation:
A=1/4√5(5+2√5) a°2=1/4√5•(5+2•√5)•15°2=387.10742 cm°2
Rounded= 387.11
Answer:
-83, -82, and -81
Step-by-step explanation:
Step 1: Declare your variable
Let x represent the largest of the 3 consecutive integer
Integer 1: x
Integer 2: x + 1
Integer 3: x + 2
Step 2: Create an equation
(x) + (x + 1) + (x + 2) = -246
Step 3: Solve
x + x + 1 + x + 2 = -246
3x + 3 = -246
3x = -249

x = -83
FInd the other 2 numbers
Integer 1: -83
Integer 2: -82
Integer 3: -81
Step 4: Therefore Statement
Therefore the 3 consecutive numbers are -83, -82, and -81
Y - 1 = m(x - 1) . . . (1)
y = mx - m + 1 . . . (2)
From(2), -m + 1 = 2 => m = 1 - 2 = -1
Substituting for m in (1), we have:
y - 1 = -(x - 1) . . . (3)
Equation of a line in general form is given by ax + by = c
From (3), y - 1 = -x + 1
x + y = 1 + 1
Therefore, required equation is x + y = 2.
In this question, angle 5 and angle 2 are linear pair. And angles of linear pair are supplementary angles .
Therefore

And sum of interior angles of a triangle is 180 degree, that is

SInce both the equations have 180 in the right side, left side of both equations are equal too . That is

Which gives

So the correct option is A .
