Answer:
value of y = 95°
Step-by-step explanation:
=》128° + 72° + 65° + y = 360°
( because sum of all angles
of a triangle = 360° )
=》265° + y = 360°
=》y = 360° - 265°
=》y = 95°
i hope you got it.
Answer:
x = 4.9 cm
Step-by-step explanation:
Note that sin theta = (opp side) / (hypotenuse), and that:
hypotenuse (opp side)
------------------ = -----------------
1 sin theta
and so:
hypotenuse (opp side) 4 cm
------------------ = ----------------- or hypotenuse = ---------------------------- = x
1 sin theta sin (55 degrees)
4 cm
Thus, x = --------------- = x = 4.88 cm or (to 1 DP) x = 4.9 cm
0.819
