If a ladder is to be placed 3 feet from the side of a house. If top of the ladder rests exactly on the edge of the house when it is placed at an angle of 72 degrees from the ground, how long is the ladder to the nearest foot?

Answers

Answer:

7 feet long

Step-by-step explanation:

This set up will give a right angle triangle where;

Length of the ladder is the hypotenuse = x

The distance of the ladder to the house is the adjacent = 3 feet

Angle of elevation theta = 72 degrees

Using the CAH in trigonometry identity;

cos theta = adjacent/hypotenuse

cos 72 = 3/hyp

hyp = 3/cos72

hyp = 3/0.4258

hyp = 7.05 feet

Hence the ladder is approximately 7 feet long

Step-by-step explanation:

3(x + 2) = -5 - 2(x - 3) *

Answers

Answer:

x = -1

Step-by-step explanation:

3(x + 2) = -5 -2(x-3)

open parenthesis

3 * x + 3 * 2 = -5 + -2 * x + -2 * -3

3x + 6 = - 5 - 2x + 6

subtract 6 from both sides

3x + 6 - 6 = -5 - 2x + 6

3x = -5 -2x

add 2x from both sides

3x + 2x = -5 - 2x + 2x

5x = -5

divide both sides of the equation by 5

5x/5 = -5/5

x = -5/5

x = -1

Consider the triangle (in which angle4 is present)

by angle sum property,

20 + 40 + angle4 = 180

60 + angle4 = 180

angle4 = 180 - 60

angle4 = 120

Also,

angle2 = 120 (vertically opposite angles)

angle1 + angle2 = 180 (linear pair)

angle1 + 120 = 180

angle1 = 180 - 120

angle1 = 60

Compared to last month, there was a 65% increase in the number of houses sold this month. There were x. number of houses sold last month. Write two expressions that can be used to determine the number of houses

Answers

Answer:

x+0.65x and x(1 + 0.65)

Step-by-step explanation:

Given

Original number of houses last month = x

If there are 65% increase in the number of houses, then;

Increment = 65% of x

Increment = 0.65x

The number of houses sold compared to last month = Original number + Increment

The number of houses sold compared to last month = x + 0.65x

This can also be expressed as x (1+ 0.65)

Hence the required expressions are x + 0.65x and x(1 + 0.65)

AXY Zand AABCare similar triangles. Given the dimensions shown in the diagram, what is the
area of AABC? Express the answer in square units.
area in square units

Answers

Answer:

3.528

Step-by-step explanation:

First, you need to determine the scale factor. Divide one side in the larger triangle by the corresponding side in the smaller triangle. For example, 8/2. This would give you a scale factor of 2. Then you can reverse the process with the dimensions you need to get the area. The height of the larger triangle is 3.36, so to find the height of the smaller one, you divide it by 2, or the scale factor, to get the height of the smaller triangle which is 1.68. Next, you can solve for area of triangle using a=bh/2, so 4.2*1.68/2=a = 3.528.
