Answer:
2
Step-by-step explanation:
24/ 11 = 2 2/11
so, we have 2 and 2/11
11x2 = 22 + 2 = 24
If cos(70) = 0.342
the cosine of the alternative angle of 70° will also give the same value
angle measure = 360 - 70 = 240°
cos (240) will also be 0.342
The length of segment of EF would be 16
Would surely like to see you begin the problem solution yourself and to share what you have done.
Let the girl's age be J and the father's F.
J=5 and F=42 now.
In x years, the father will be twice as old as the girl.
We write that as F + x = 2( J + x), or 42 + x = 2( 5 + x)
Then 42 + x = 10 + 2x => x = 32
check: is 42+32 = 2(5+32)? Is 74 = 2(37)? YES.
The answer: "5 years from now."
Let the longest side of ΔABC is c = 24 and the longest side of ΔXYZ is z = 60
The ratio of any pair of corresponding sides of these triangles is the same:
z/c = 60/24 = 2.5
x = 10 · 2.5 = 25
y = 20 · 2.5 = 50
The perimeter of ΔXYZ : 25 + 50 + 60 = 135 units
hc = 8
hz = 8 · 2.5 = 20
The area of ΔXYZ : 60 · 20 / 2 = 600 square units
