Answer:
It is SSS
You already have the two sides, and you can see the two triangles share a common line. Therefore you know the unknown is a side.
Given the Mean Age of Five Children = 12
⇒ Total Age of the Chidren = 12 × 5 = 60 Years
Answer:
I won't write it in paragraph but use this:
- angle A + angle B + angle C = 180 so when one angle is missing add the other 2 and subtract it to 180, that would be the answer for the missing angle; applies only to triangle (all kinds)
- if its the exterior angle, add them all like the one above but subtract it instead to any shapes or if it is adjacent to a given degree, you can always subtract it to 180 to get the exterior
- if its a different shape, count the sides and subtract it by two then multiply by 180; thats the degree for the total angles of the shape
- if its variable, do the third one (unless you know what it is) add them all like the first one and subtract to the answer in the #3
Answer:
F = 6x
O = -3x
I = 10x
L = -5
Step-by-step explanation:
FOIL follows the formula:
(a + b)(c + d) = ac + ad + bc+ bd
