Answer:
hello
3 x + 50 = 6 x - 10
3 x - 6 x = - 10 - 50
- 3 x = - 60
x = 20
Step-by-step explanation:
Try C... idk.. it might be D too so just take yo best guess but in my opinion ig its C
Answer:

Step-by-step explanation:
sum of interior angles in a triangle is 180 degree
interior angles are (5x+3y)∘,(3x+20)∘, and (10y+30)
add all the angles and make it equal to 180

combine like terms


subtract 50 from both sides

Answer:
option b 5√2
option a 20
option c 4
option d 3/4
option b 3
Step-by-step explanation:
To solve all these questions we will use trigonometry identity which says that
sinΔ = opposite / hypotenuse
1)
sin45 = 5 / KL
Kl = 
KL = 5√2
2)
TanФ = opp / adj
Ф = Tan^-1(5/14)
Ф = 19.65
≈ 20
3)
sin(30) = rq / 8
rq = sin(30)(8)
rq = 4
4)
tan(Ф) = 6/8
5)
angle 3
