Answer:

x=35°

Step-by-step explanation:

40° + 3x° + x°= 180°

40° + 4x° =180°

4x° = 180° - 40°

4x° = 140°

x° = 35°

From least to greatest :

x=35°

3x=35×3

=105°

therefore in order : 35°, 40°, 105°

Answer: See steps below for answer

Step-by-step explanation:

1) Set up an equation

40 + x + 3x = 180
4x + 40 = 180
4x = 140
x = 35

_____

Part 2:

One angle: 40 degrees

Second angle: x or 35 degrees

Third angle: 3x or 105 degrees

Therefore answer is

35, 40, 105

Suppose the radius of a circle is 8. What is its area?

monitta

The Formula to find the Area of a circle using the radius is:
$A = \pi r^2$

r = 8
So:
$A = \pi r^2$
$A = \pi 8^2$
$A = \pi64$

And you get about 201.06193

So, the area of a circle with a radius of 8 is about 201.06

Hope this Helps :)

Three functions are given below: f(x), g(x), and h(x). Find the axis of symmetry for each function, and rank the functions based

m_a_m_a [10]

Answer:

Step-by-step explanation:

f(x)=-4(x-2)²+3

put x-2=0

axis of symmetry is x=2

g(x)=-2(x²+8x)+15

=-2(x²+8x+4²-4²)+15

=-2(x+4)²+32+15

=-2(x+4)²+47

put x+4=0

axis of symmetry is x=-4

h(x) is minimum at x=1

axis of symmetry is x=1
