Let the number of red skittles be = x
Let the number of orange skittles be = y
Red skittles are 10 less than orange, this gives
x = y-10................(i)
Orange Skittles are twice the number of red skittles, this gives
y = 2x.............(ii)
Incorporating the value of y from second equation into first
x = 2x - 10
hence, x = 10
Now putting the value of x in equation second
y = 2x
y = 2*10
y = 20
Hence, the number of red skittles are 10 and the number of orange skittles are 20.

Answer:
look at the horizontal line in the picture. the degree measure of any line is 180° given there's a perpendicular ray through that horizontal line it's therfore split into two sides both with angle measure of 90°.
given f is 71° then g can be found knowing that both g and f must add to 90°. 71+g=90. g=19°
now look at f again. f and d are what's known as vertical angles and that means that they're angle measures are congruent. therfore the measure of d is 71° d=71°
Finally to find e we notice that angle d and e form a straight line which means both angles measures must add to 180°. therefore e can be found by computing d+e=180
aunaitituitmg our information we know 71+e=180 then e must equal 109° e=109°
