Step-by-step explanation:

always draw triangle b first. for triangle b it is reflected across the x-axis which means all y valies become negative. then for triangle c, you swap the x and y values around.

The two triangle­shaped gardens are congruent. Find all of the missing side lengths and angle measures. Show any necessary work
pantera1 [17]
The two figures are in the file attached.

Congruency means that all the respcetive sides and angles are equals.

Then, the three angles are :

y = 38°

x = 90°

w = 180° - 90° - 38° = 52


The three sides are:

z= 10yd
v= 7.9yd
u=6.2yd


You have all the measures as a function of yd, but you do not have any information about yd, then it is not possible to find the real lenghts.

All you can tell is that the sides obey Pythagoream theorem:

u^2 + v^2 = z^2   

But that is not enough to find one side, because you do not know any of them.

For example if you apply Pytagorean theorem you cand do"

(7.9yd)^2 + (6.2)^2 = (10yd)^2

but that cannot be solved for yd, because they are factors of all the terms in both sides, which mean that they cancel to obtain:

(7.9)^2 + (6.2)^2 = (10)^2, which is not any new information.

Also you can think about sine theorem, but it does not help, because you also need one side.


Then you only can tell the missing angles, as I have shown, but not the misssing lengths.

Ivan has a summer babysitting job that pays $15 per hour. He wants to know how many hours he has to babysit to afford a new bike
exis [7]

Answer: 20 hours

Step-by-step explanation:

Equation: 15x = 300

Isolate the variable.

Divide both sides by 15:   ¹⁵ˣ⁄₁₅ = ³⁰⁰⁄₁₅

x = 20

Ivan needs to work 20 hours in order to afford the bicycle.

The scale of a map is 1 inch to 175 miles the actual distance between Chicago Illinois in Pittsburgh PA is 375 miles find the di
aleksklad [387]

<u>Given</u>:

A map shows some cities in the northern United States. The scale of a map is 1 \ inch: 125 \ miles

The actual distance between Chicago, IL and Pittsburgh, PA is 375 miles.

We need to determine the distance between the two cities on the map.

<u>Distance between the two cities:</u>

The distance between the two cities on the map can be determined by dividing the actual distance by 125 miles.

Thus, we have;

Distance=\frac{375}{125}

Dividing the terms, we get;

Distance = 3

Thus, the distance between the two cities on the map is 3 inch.

Which of the following is the graph of y= - x + 1
Ksivusya [100]

Answer:

See picture below

Step-by-step explanation:

To graph properly, remember that:

  • The y intercept of the function, is the value of the function when x=0, and tells (in this case y=1 is the intercept). Locate this point in the graph.
  • The x intercept, which is the value of x when y=0 is x=1. Locate it in the graph.
  • You now have two points of a straight line: join this two points and you would have done it!
