Realize the tangent function has a period of 180°, so when your calculator (or memory) tells you
.. θ = arctan(-1)
.. θ = -45°
you can translate that value into the desired range by adding multiples of 180° to get the two solutions ...
.. θ = 135°
.. θ = 315°

How many triangles can be constructed with angles measuring 50º, 90º, and 40º?
NeX [460]

Answer: Infinite


Step-by-step explanation:

We know that in a triangle the sum of all the interior angles must be 180°.

The given angles 50º, 90º and 40º

The sum of the angles 50º+ 90º + 40º= 180°

Thus, a triangle is possible with the given measurement.,

Let there is another triangle with the given angles, then by AAA similarity criteria they are similar.

Similarly, all the triangles with the same measurements of the angles must be similar.

Therefore, there are infinite number of triangles can be possible with angles measuring 50º, 90º, and 40º.

Ryan bought a brand new car for $18,000. Its value depreciated at a rate of 1.2%.
kirza4 [7]

Answer:

A(t)= 18000(0.988)^t

Step-by-step explanation:

Given data

Ryan bought a brand new car for $18,000

Its value depreciated at a rate of 1.2%

Let us use the compound expression

A= P(1-r)^t

substitute

A= 18000(1-0.012)^t

A(t)= 18000(0.988)^t

Hence the expression is A(t)= 18000(0.988)^t

How do you do this ?
jeka57 [31]

Answer: 3(x^2 + 4)/(x - 5)(x + 4)

Step-by-step explanation:

To simplify, begin with 3x^2 + 12 by dividing by 3 first: 3(x^2 + 4)

x^2 - x - 20 can be simplified into (x - 5) (x + 4). To find these terms, you have to figure out what two numbers multiply together to equal -20 but also add to -1.

Jade and Eliza went shopping at a mall. Jade spent $10 more than 5 times the amount that Eliza spent. Jade spent a total of $150
DaniilM [7]

Answer:

140

Step-by-step explanation:

Let total money spent by Eliza's be represented as x

Five times amount Eliza spent = 5x and total amount spent by Jade is $150

So it will be $10+ 5x =$150

5x= 150- 10

5x= 140

x = 140÷5

x= 28

........................

So therefore Eliza's amount spent = $28 and

5x$28 = $140

Jade spent $10 more equals $10+$140= $150(Total money spent by Jade).
