A<u> triangle</u> is a <em>plane shape</em> bounded by three straight sides, thus it has three internal <em>angles</em>. Therefore, the required <em>values</em> are:
i. x = 
ii. y = 
A <em>plane shape</em> is a figure bounded by<u> straight</u> sides. Examples are triangles, squares, rectangles, rhombus, kite, trapezium, etc. A triangle is an example of a plane shape that has three<em> sides</em>, thus three <u>angles.</u> also, the sum of <em>angles</em> in a given triangle is
.
Thus the required values of x and y can be determined as follows:
x + 20 + 120 = 
x + 140 = 
x =
- 140
So that,
x = 
Thus,
y = 20 + 120 (the sum of<em> opposite</em> angles is <em>equal</em> to an exterior angle.)
= 
Therefore, x =
and y =

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
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.
