Answer:
I'm confused too I'm sorry
Subtract 2d from both sides
simplify 10 + 2.5d - 2d to 10 + 0.5d
subtract 10 from both sides
simplify 4 - 10 to -6
divide both sides by 0.5
simplify 6/0.5 to 12
switch the sides
Answer: d = -12.
Answer:
x = 17
, y = 34
Step-by-step explanation:
Since the triangle is right use trig ratios to find x and y
note exact values sin30° =
, tan30° = 
sin30° =
= 
multiply both sides by y
y sin30° = 17 ( divide both sides by sin30° )
y =
= 34
tan30° =
= 
multiply both sides by x
x tan30° = 17 ( divide both sides by tan30° )
x =
= 17
