The angle 1 and the side equal to 72° together equal 180. 72 + x = 180 using the subtraction property of equality we can conclude that x = 108.

Side 2 is parallel with 72° making them equal and Side 3 is parallel with 108° making them equal.

Side 1 = 108°
Side 2 = 72°
Side 3 = 108°

Answer:

A. 3t = 24

Step-by-step explanation:

$24 is the total amount spent.

3. Using the net, calculate and label the area of each face of the prism.

AysviL [449]

Answer:

Finding the areas of each of the rectangles and squares of the net of a rectangular prism and adding up those areas gives the surface area or total surface area of the prism. For example, if the length of one side of the cube 4 units then the area of one its face is 4 × 4 = 16 square units.

Can someone help me learn to solve this?

kondaur [170]

Answer:

x = 110°

Step-by-step explanation:

Given that AB = AD then Δ ABD is isosceles and the base angles are congruent, that is

∠ ABD = ∠ ADB = 35°

The sum of the 3 angles in the triangle = 180°, that is

x + 35° + 35° = 180°

x + 70° = 180° ( subtract 70° from both sides )

x = 110°

Find the value of two numbers if their sum is 12 and their difference is 4

IrinaK [193]

X + y = 12
x - y = 4
-----------------add
2x = 16
x = 8

x - y = 4
8 - y = 4
y = 4

answer
two numbers: 8 and 4

doule check
sum = 8 + 4 = 12
difference = 8 - 4 = 4

Draw a line for the axis of symmetry of function f. Also mark the x-intercept(s), y-intercept, and vertex of the function. f(x)

lilavasa [31]

Answer:

Part A: vertex at (-1,4)

Part B: line of symmetry x =-1

Part C: x-intercept x = -3 and x = 1

Part D: y-intercept y = 3

Step-by-step explanation:

Given f(x) = - (x+1)² + 4

The given equation represents a parabola.

The general equation of the parabola with a vertex at (h,k)

f(x) = (x-h)² + k

Part A: To find the vertex, compare the general equation with the given function.

So, the vertex of the function will be at (-1,4)

Part B: the line for the axis of symmetry of function will be at x =-1

Part C: To find x-intercept, put y = 0

So, - (x+1)² + 4 = 0

- (x+1)² = -4

(x+1)² = 4

x + 1 = ±√4 = ±2

x + 1 = 2 OR x + 1 = -2

x = 1 OR x =-3

x-intercept at x = 1 and x = -3

Part D:To find y-intercept, put x = 0

So, y = - (0+1)² + 4 = -1 + 4 = 3

y-intercept at y = 3

See the attached figure.
