Opposite angle of a quadrilateral add up to 180 degrees.
This means Angle A plus Angle C equal 180.
We can solve for X using that, then solve for Angle B.
2x-7 + x +4 = 180
Simplify:
3x -3 = 180
Add 3 to each side:
3x = 183
Divide both sides by 3:
x = 183 /3
x = 61
Now we know x, replace x with 61 in the equation for Angle B:
Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.
Answer A
Step-by-step explanation:
Because there is a zero at the begining.
Given:
Base area = 4π mm²
Height = 10 mm
To find:
The volume of the cylinder.
Solution:
Base of the cylinder is circle.
Area of the base = πr²
πr² = 4π
Volume of the cylinder = πr²h
Substitute 4π in place of πr².
= 4π × 10
= 40π mm³
The volume of the cylinder is 40π mm³.
X^2 = 16
x = 4
x = -4
good luck :)
Y = the square root of x minus 2 is portrayed in the file attached below.
As you can see, the domain (x value) begins at 2. We can use interval notation to say that the domain is [2, infinity) Infinity because it will stretch out to infinity. While the range will be [0,infinity) (message me if you don't recognize these concepts please.)
