Answer:
139 degrees
Step-by-step explanation:
Supplementary angles mean that the sum of the two angles should add up to 180 degrees. Since one of the angles is given, 41 degrees, and you know that the sum should be 180 degrees, you are able to find the measure of the unknown angle QRS.
41 + QRS = 180
QRS = 139 degrees
g - 3/7 = 2/7 is an equation.
8 is the median. If yo line up the numbers from least to greatest you will get 2,4,6,8,8,10,12 and the middle number is 8.
Answer:
x = -3.73 or -0.27
Step-by-step explanation:
From the question,
x²+ 4x+1 = 0
This is a quadratic equation, and it can be solved using any of the 3 methods.
Using completing the square method,
x²+4x = -1
Add half the coeffiecient of x, square it and add it to both side of the equation.
The coefficient of x is 4,
half the cofficient is 2
Add 2² to both side of the equation
x²+4x+2² = -1+2²
(x+2)² = 3
x+2 = ±√3
x+2 = ±1.73
Either,
x+2 = -1.73
x = -1.73-2
x = -3.73
or
x+2 = +1.73
x = =1.73-2
x = -0.27
