Answer:
Answer below in picture:-
Hope it helps.
3 equivalent fractions are 4/10 , 10/25 and , 6/15
900,000,000. move the decimal until you have a number between 1-10 so move it 8 times and you'll have 9×10^8
The last pair.
Because 2*4/3*4=8/12
Answer:
3/5
Step-by-step explanation:
sin theta=opposite/hypotenuse
4/5=opposite/hypotenuse
therefore opposite=4 and hypotenuse=5
for adjacent
using pythagoras theorem
a^2+b^2=c^2
opposite^2 + adjacent^2 =hypotenuse^2
4^2 + adjacent^2 =5^2
16 + adjacent^2 =25
adjacent^2 =25-16
adjacent =
adjacent=3
cos theta=adjacent/hypotenuse
=3/5
therefore the value of cos theta is 3/5
