Is it the third one?
Step-by-step explanation:
Answer:
4.33333333333
Step-by-step explanation:
Answer:
m = 6
, n = 6
Step-by-step explanation:
Using the sine and cosine ratios in the right triangle and exact values
cos30° =
, sin30° =
, then
cos30° =
=
=
( cross- multiply )
2m = 12
( divide both sides by 2 )
m = 6![\sqrt{3}](https://tex.z-dn.net/?f=%5Csqrt%7B3%7D)
and
sin30° =
=
=
( cross- multiply )
2n = 12 ( divide both sides by 2 )
n = 6
Answer:
127/14
Step-by-step explanation:
39/7 + 7/2 = 78/14 + 49/14
78/14 +49/14 = 127/14
I'm not to sure but this is what I got....
1. 2=7x+7
-7 -7
-5/7= 7x/7 What you do to one side you always do to the other.
x = -5/7
2. 3/5 = 5y/5
y = 3/5
Hope it helped! : )
