Ответ:
Length p = 6.1
Step-by-step explanation:
Sine R /r = Sine P/p
Angle R = 135 degrees
Length r = 9.5
Angle P = 27 degrees
Length p = ?
Therefore ,
Sine 135 deg. /9.5 = sine 27 degrees/ p
0.7071/9.5 = 0.4540/p
0.0744 = 0.4540/p
Cross multiply
p x 0.0744 = 0.4540
Divide both sides by 0.0744
p = 0.4540/0.0744
p = 6.1
