SOMEONE PLEASE HELP QUICKLY!!! I’LL MARK BRAINLIEST

Answer 1

Answer:

x=18.5 y=14.2

Step-by-step explanation:

The unmarked angle for the top/x triangle is 109 (all angles add up to 180, 180-50-21=109)

Use cosine rule:

(a/sina)=(b/sinb)

(x/sin109)=(15/sin50)

(x/sin109)=19.58110934

x=18.51430261

The top-most angle of the bottom/y triangle is 71 (angles on a straight line are 180, 180-109=71)

The righthand angle of the bottom/y triangle is 19 (angles in a triangle add to 180, 180-71-90=19)

Use cosine rule again:

(a/sina)=(b/sinb)

(y/sin71)=(15/sin90)

y/sin71=15

y=14.18277863
