The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 360 degrees.
1 answer:
Answer: False
Step-by-step explanation:
Triangle is a polygon with 3 sides. The formula for calculating the sum of angle in a polygon is given as :
where n is the number of sides , so to calculate the sum of angles in a triangle we have :
= 1 x 180
= 180
Therefore : The triangle angle sum property states that the measures of the 3 angles of any triangle must add to 180 degrees.

Step-by-step explanation:
We need to solve for x in the equation
cos (x+ pi) ^2 = sin (x)
cos (x+ pi) = - cos(x)
(-cos (x)) * (-cos (x)) = sin(x)
cos(x) ^2 = sin(x)
We know that
cos(x) ^2 + sin(x) ^2 = 1
cos(x) ^2 = 1 - sin(x) ^2
1 - sin(x) ^2 = sin(x)
sin(x) ^2 + sin (x) -1 = 0
Let A = sin(x)
A^2 + A - 1 = 0
(solutions attached in picture 1)
This means that
x = arcsin(A)

What logarithmic equation has the same solution as x-4=2^3
Solution:
x-4=2³
x-4=2*2*2
x-4=8
TO solve for x, Let us add 4 on both sides
x-4+4=8+4
x+0=12
So, x=12
But, x=12 is not a logarithmic equation and there are no options
So, an equation like, x=㏒
As log has base 10,
So, x=㏒ =12
So, logarithmic equation like x=log has same solution as x-4=2³
