Answer:
a=72° b = 6°
Step-by-step explanation:
answer is in pic
(2/5)+(3/(5x))=(x+5)/10
nasty fractions, we hates it forever
so
get rid of all those nasty fractions
multiply both sides by 10x
4x+6=x(x+5)
distribute
4x+6=x^2+5x
minus (4x+6) from both sides
0=x^2+x-6
factor
0=(x-2)(x+3)
set each to zero
0=x-2
2=x
0=x+3
-3=x
x=-3 and 2
3rd option is answer
Answer:
you can find angle E by
Step-by-step explanation:
sum of angles of traingle is 180 degree
Tangent ratio is the opposite side/adjacent side.
In relation to Angle A: The opposite side has a length of 2 and the adjacent side has a length of 3.
Tan A = 2/3
