Answer:
X = 13.13 feet
Step-by-step explanation:
Let the distance between Lila and Mark be x.
Let the distance between Avery and lila be A= 20
Let the distance between Avery and Mark be B= 30
Angle x = 200-180=20°
To solve this question we will use the cosine formula which is
X² = A²+ B² -2ABcosx
X²= 20² + 30² -2(20)(30)cos20
X²=1300-1127.6
X²= 172.4
X= 13.13
The answer is D. 4x7+5=33 8x7+5=61. Hope it helps
h=9
A=((a+b)/2)h
234=((32+20)/2)h
234=(52/2)h
234=26h
9=h
Answer:
-3/4 pi radians
Step-by-step explanation:
<em>180° is 1 pi radian</em>
Hence, -<em>135° = -135/180 pi radians</em>
= -0.75 pi radians
= -3/4 pi radians
