Common ratio = a2 / a1 or a3/a2
= 16/64 = 1/4
In short, Your Answer would be 1/4
Hope this helps!
To find the value of x we use sine rule given by
a/sin A=b/sin B=c/sinC
the value of x will be given by:
∠F=180-(127)=53°
13/sin 53=x/sin 87
solving for x we get
x=[13sin 87]/sin 53
x=16.2555~16.3 cm
Answer: m∠EFG=83°
m∠GFH =97°
Step-by-step explanation:
Given : ∠EFG and ∠GFH are a linear pair.
m∠EFG=3n+23, and m∠GFH=4n+17.
We know that linear pair of angles added up to 180 degrees.
i.e
Now, m∠EFG=(3n+23)°= (3(20)+23)°=(60+23)°=83°
m∠GFH =(4n+17)°=(4(20)+17)°=(80+17)°=97°
Answer:
option 1
Step-by-step explanation:
It's given in the question that
a (first term of an A.P.) = 14
d (common difference between terms of A.P.) = -3
So,
2nd term will be = a + d = 14 + (-3) = 11
3rd term = a + 2d = 14 + 2×(-3) = 8
4th term = a + 3d = 14 + 3×(-3) = 5
All these terms are matching with option 1. So, option 1 is the correct option
