A triangle is a plane shape bounded by three straight sides, thus it has three internal angles. Therefore, the required values are:

i. x = $40^{o}$

ii. y = $120^{o}$

A plane shape is a figure bounded by straight sides. Examples are triangles, squares, rectangles, rhombus, kite, trapezium, etc. A triangle is an example of a plane shape that has three sides, thus three angles. also, the sum of angles in a given triangle is $180^{o}$ .

Thus the required values of x and y can be determined as follows:

x + 20 + 120 = $180^{o}$

x + 140 = $180^{o}$

x = $180^{o}$ - 140

So that,

x = $40^{o}$

Thus,

y = 20 + 120 (the sum of opposite angles is equal to an exterior angle.)

= $120^{o}$

Therefore, x = $40^{o}$ and y = $120^{o}$

Given that F(x) =x^2+2, evaluate F(2)

maria [59]

Answer:

F(2) = 6

Step-by-step explanation:

Given that F(x) =x^2+2, evaluate F(2).

The above equation is a function of x

Such that for every value of x at a given time, the equation results to equation takes a different value at that time. For every value of x, the value is simply substituted into the equation to find the solution of the equation at that point. The above equation is a quadratic function since the highest power of x is 2.

F(x) =x^2+2,

To evaluate F(2),

Substitute x = 2 in equation x^2+2

It becomes

2^2 + 2 = 4 + 2 = 6

So F(2) = 6

Solve each pair of simulation equation.Giving both solutions. Multiply both equations by suitable numbers before adding/subtract

pashok25 [27]

Answer:

Step-by-step explanation:

I haven't got time to do all these by I'll give you the method in each case.

You have to make the x or y term equal (or 1 term + and other -) in both equations before adding or subtracting.

A . Multiply equation 2 by 2 and subtract (to eliminate x)

- don't forget to multiply EACH TERM by 2.

B. Multiply equation 2 by -2 and add.

C. Multiply equation 1 by 3 and equation 2 by 2 ( this will give -6y and +6y in the resulting equations ) so you then add to eliminate y.

D. Multiply equation 1 by 13 and equation and equation 2 by 2 to eliminate x then add.
