Answer:
85°
Step-by-step explanation:
The triangle pictured is an isosceles triangle because side KJ = LJ.
this means that ∠JKL = ∠JLK = x°
Also recall that all interior angles of a triangle add up to 180°
Hence,
180° = ∠JKL + ∠JLK + ∠KJL
180 = x + x + 10
180 = 2x + 10 (subtract 10 from both sides and rearrange)
2x = 180 - 10
2x = 170 (divide both sides by 2)
x = 170 / 2 = 85°
First 2 are true and others are false
Answer:
tan 5\4
Step-by-step explanation:
on number 1 use TOA which is Tan 4\5 if not 5\4
Answer:
306 km
Step-by-step explanation:
put both of them to equal in ratio form so now
85 / (7/6) = x / (21/5)
85 * (21/5) = 7/6x
357 = 7/6x
x = 306 km
