Answer:
3
Step-by-step explanation:
You divide 45 and 60 then you mutliple the number by 4 then find your anser after you done sovled this is how you solve it divided by 60=0.75 mutiply by 4=3 3 or 4/3
let the unknown angle be a
so a+90 + 20= 180
If we take 70°,then area (A)=
If we take 90° then area(A)=
[tex] \frac{1}{2} sin90x \times 10 = \frn
therefore y=10.64 cm
By using pythagoras theorem
y^2=x^2+10^2
or, x^2=y^2-100
or, x^2=10.64^2-100
or,x^2=13.2096
or, x= 3.63 cm
Answer:
20 animals = x chickens (2 legs) + y horses (4 legs).
x+y=20 (total number of animals)
2x+4y=64 *total number of legs)
x+y=20
x+2y=32
If you solve this system of animal with 2 and 4 legs, you get 6 chickens and 14 horses
x=6
y=14
