Step-by-step explanation:
Alright, lets get started.
using Sine Law,
Another angle will be
considering angle B, angle C =
considering angle B', angle C' =
Similarly, finding c'
Hence two triangles are possible with below details: : Answer
A = 30, B = 48.6, C = 101.4, c = 7.84
A = 30, B' = 131.4, C' = 18.6, c' = 2.55

Answer:
y ≈ 5.2
Step-by-step explanation:
∠ F = 180° - (42 + 48)° ← sum of angles in a triangle
∠ F = 180° - 90° = 90°
Thus Δ DEF is right at F
Using the sine ratio in the right triangle
sin48° = =
=
( multiply both sides by 7 )
7 × sin48° = y , then
y ≈ 5.2 ( to the nearest tenth )
