Answer:
A=8
Step-by-step explanation:
If you use the formula 30-60-90 which is a-radical 3a-2a
since the hypotenuse is 2a it equals 16
therefore if its 2a all you need to do is divide it where then you get 8.
The known figures that make up this unknown figure are a trapezoid and a half circle.
Answer:
(A) 66k+9
Step-by-step explanation:
50k+5+4+16k
First distribute 3(8-6n):
3(8 - 6n) = 42
24 - 18n = 42
Now subtract 24 from both sides:
-18n = 18
And divide both sides by -18 to finally isolate n:
n = -1
