Answer:
8.212°
Step-by-step explanation:
Hypotenuse^2=base^2+perp^2
(8)^2=(7)^2+(perp)^2
64=49+(perp)^2
64/49=perp^2
1.306=perp^2
Now taking sq root on both sides
Perp=√1.306
Perp=1.142
Sin C=opposite/hypotenuse
Sin C=1.142/8
Sin C=0.14285
C=Sin^-1 0.14285
C=8.212°
Answer:
1,3
Step-by-step explanation:
Answer:
first one and the biology one
Answer:
As shown in picture, AC is tangent to circle O
=> angle BAC = 90 deg
As the property of angle on circle:
=> BAY = (1/2) arc BY = (1/2) x 52 = 26 deg
=> angle YAC = angle BAC - angle BAY = 90 - 26 = 64 deg
Hope this helps!
