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 = $120^{o}$

Rita is 8 years older than Fati. If Fati is 15 years now, how old was Rita 3 years ago

ivanzaharov [21]

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.

Simplify 8^ -5 over 8^ -3 <-- this is a fraction

pochemuha

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

Does (2, -1) make this a true statement? Why or why not? 3x + 2y = 4

kvv77 [185]

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.
