Answer:
<h2>107 and 73</h2><h2 />
Step-by-step explanation:
supplementary angle
7x + 9 + 5x + 3 = 180
12x = 180 - 3 - 9
x = 168 / 12
x = 14
plugin x=14 into the equation
= 7x + 9
= 7(14) + 9
= 107°
plugin x=14 into the equation
= 5x + 3
= 5(14) + 3
= 73°

Answer:
4.36
Step-by-step explanation:
14z-3-6-52 (Add all the numbers with the negative sign together)
= 14z-61 (Equation equals 0)
0 = 14z - 61 (Add 61 to zero)
0+61 = 14z ( Note :- the negative sign before 61 changes to +ve upon moving to the left hand side)
61 = 14z (Divide both sides by 14)
61/14 = 14/14
4.357 = z
z = 4.36
