Answer:
Q9 X=42.5
Step-by-step explanation:
let unknown angle be x
cos x=45/61
X=cos^-1 45/61
X=42.463...
X=42.5 (1 decimal place)
Answer:
if 1 ant has 6 legs, then multiply. 6x8 is 48
Step-by-step explanation:
10) S is the midpoint of RT.
Sx= Rx+Tx/2=2
Tx=13
Sy=Ry+Ty/2= -1
Ty= -1
T=(13,-1)
11) Sx=Rx+Tx/2=-4
Rx= -1
Sy=Ry+Ty/2= -6
Ry= -9
R=(-1,-9)
12)B is midpoint of AC.
Bx= Ax+Cx/2=-5
By= Ay+Cx/2= 1
B=(-5,1)
E is midpoint of BD.
Ex= Bx+Dx/2=-4
Dx=-3
Ey=By+Dy/2=-3
Dy=-7
D=(-3,-7)
Answer:
The correct answer is option A. 25°
Step-by-step explanation:
From the figure we can see an isosceles triangle. FGE
<G = 65° (given)
m<G = m<E = 65°
<u>To find the value of m<HFE</u>
Consider the triangle FHE in the figure we get,
m<E + m<HFE + m<FHE = 180
m<HFE = 180 - (m<E + m<FHE)
= 180 - (65 + 90) = 25°
Therefore m<HFE = 25°
The correct answer is option A. 25°
