Please show me how to do the check from 1 2 3

m=0.9

z=7

x=12

hope this help

and pls brainiest

Step-by-step explanation:

Pls brainiest

4m/2-3=m/3

4m-3=m/3 *2

12m-9=2m

10m=9

m=0.9

z+4/6 +z=10

z+4+6z=60

7z=56

z=7

3x/4 -2x/3=1

3x-2x/3*4=4

9x-8x=12

x=12

(1. 1 4/5 (2. 53/6=10 (3. X=12

Step-by-step explanation:

you would use (d.) the law of cosines or a^2 = b^2 + c^2 – 2bc(cos a)

, b^2 = a^2 + c^2 – 2ac(cos b), or c^2 = a^2 + b^2 - 2ab(cos c). you wouldn't use b. the law of sines as it is mostly effective when 1side and 2angles are given. a and c aren't the answer for they are the improper versions of the law of cosines. hope this is .
