<h3>Answer:  x = 40</h3>

===================================================

Work Shown:

A+B+C = 180 ..... three angles of any triangle add to 180

(2x+10)+(x)+(2x-30) = 180

5x-20 = 180

5x = 180+20 .... adding 20 to both sides

5x = 200

x = 200/5 ... dividing both sides by 5

x = 40

This is the measure of angle B

We can stop here.

If you need to know the values of the other angles, then,

  • angle A = 2x+10 = 2*40+10 = 90
  • angle C = 2x-30 = 2*40-30 = 50

Then note how A+B+C = 90+40+50 = 90+90 = 180 which helps confirm our answer.

In Exercise, describe how the graph of g is related to the graph of f.<br> g(x)=-1+f(x)
Jet001 [13]

Answer:

The graph of g is the graph of f shifted down 1 unit.

Step-by-step explanation:

Suppose you have a function y = f(x), you can do these following operations on the function:

Shift up a units: y = f(x) + a

Shift down a units: y = f(x) - a

Shift left a units: y = f(x + a)

Shift right a units: y = f(x - a)

In this problem, we have that:

g(x) = -1 + f(x) = f(x) - 1

So the graph of g is the graph of f shifted down 1 unit.

Use the drop-down menus to complete the statements. Fossils on continents that are now separated by support the theory of contin
damaskus [11]

oceans, tropical plants, Europe

Step-by-step explanation:

Fossils on continents that are now separated by oceans support the theory of continental drift. Continents closer to the equator have warmer climates, yet fossils of tropical plants have been found on islands near the North Pole. This supports the idea that islands drifted from the equator. Coal fields in Europe match those found in North America, supporting the theory of continental drift.

The theory of continental drift was proposed by Alfred Wegener in the early part of 20th century. He suggested that the continents have once been joined together as a single landmass but have drifted to their current positions today.

  • Fresh water fossils of organisms like Mesosaurus was found in parts of South America and Southern Africa. These organisms could not have swim between the oceans since they are localized to freshwater environments.
  • Tropical plants have also been found in regions of the north pole.
  • Coal fields in north America correlated with those in South America and this provided support to the theory of continental drift by Wegener.
  • He also fitted the the world into a giant puzzle to support his claim.

VladimirAG [237]
A.450.80

Multiply 40x9.80=392

Take 1/2 of 9.80 that equal 4.90
4.90 plus 9.80 $14.70x4=58.80
$58.80 plus 392 equals 450.80
