Triangle MNP has vertices N(2, 2) and P(0, –2). The triangle is symmetric about the y-axis. What is the approximate measure of t
Evgesh-ka [11]
Point M of the triangle is (-2,2) to make triangle MNP as shown in the attached image

Triangle MNP has a base of 4 units and a height of 4 units. We can work out the angle x and angle y using trigonometry ratio

We use tan ratio to find both angles

Tan (x) = \frac{opposite}{adjacent}
Tan(x)= \frac{4}{2}
Tan(x)=2
Tan^{-1}(2)=63.43494882
Angle x=63.43

Tan(y)= \frac{opposite}{adjacent}
Tan(y)= \frac{2}{4}
Tan^{-1}(0.5)=26.56505118
Angle y=26.6

Angle MNP = Angle NMP = 63.43 degrees (this is based on the fact that the triangle is an isosceles triangle)

Angle MPN = 2×26.6 = 53.2 degrees (we multiply by 2 as angle y is only a half of angle MPN - as shown in the diagram)

Answer:

150+12x=630

Step-by-step explanation:

The x represents the amount of months and it is multiplied by 12 because each month costs 12$. 150 have to be paid up front and this added to the monthly fee is equal to 630$

Please help me with this..
AleksandrR [38]

Answer:

f = 1

Step-by-step explanation:

Use the method of cross- multiplication

\frac{a}{b} = \frac{c}{d} ⇒ ad = bc, thus

20f = 5(f + 3) ← distribute

20f = 5f + 15 ( subtract 5f from both sides )

15f = 15 ( divide both sides by 15 )

f = 1
