Answer:
Angle in radian = 0.75
Step-by-step explanation:
Given:
Height = 11 ft
Hypotenuse = 15 ft
Find:
Angle in radian
Computation:
Cosθ = Height / Hypotenuse
Cosθ = 11/ 15
Angle in radian = 0.75
Answer:
A or B
Step-by-step explanation:
.6 is greater than .5 just like how 6 is greater than 5. If it's negative though, its the opposite!
R=rita's age
m=mother's age
g=grandmother's age
mother is 4 times as old as rita
m=4r
grandmother is 2 times as old as mother
g=2m
sum is 104
r+m+g=104
subsitute 4r for m and 2m for g
r+4r+2m=104
subsitute 4r for m
r+4r+2(4r)=104
r+4r+8r=104
13r=104
divide both sides by 13
r=8
4r=m=32
8r=2m=g=64
rita is 8
mother is 32
grandmother is 64
