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 =

Edit- The answer is according to question before questioner edited, its not a wrong solution just diffrent question
Answer:
Rita is 20 years old
Step-by-step explanation:
If you add 8 years to Fati's age, (15+8), you get 23. That is Rita's age right now. Now subtract 3 from 23. You get 20. So Rita is 20 years old.
Ok, 8^(-5) divided by 8^(-3) would be 8^(-5-(-3)), because when you divide numbers with the same base, you subtract the exponents. That would be 8^(-2), which I suppose is A
Answer: Yes
Step-by-step explanation:
So a coordinate pair is always set up (x,y) so you plug the x term in the coordinate pair into the x in the equation and the y term in for the y. 3×2 + 2×-1. Multiply them together and you end up with 4.
