Answer:
8. x = 16
9. x = 10
14.
m ∠RSU = 130°
m ∠UST = 50°
15.
m ∠RSU = 124°
m ∠UST = 56°
Step-by-step explanation:
8.
Given ∠DEF is bisected by EG. That is , ∠DEG = ∠GEF
That is , (x + 15)° = 31°
x = 31 - 15 = 16
9.
Given ∠DEF is bisected by EG. That is , ∠DEG = ∠GEF
That is ,
(6x - 4)° = 56°
6x = 56 + 4
6x = 60
x = 10
14.
13x + 5x = 180° [straight line angles ]
18x = 180
x = 10
m ∠RSU = 130°
m ∠UST = 50°
15.
4x + 12 + 2x = 180° [ straight line angles]
6x = 180 - 12
6x = 168
x = 28
m ∠RSU = 4(28) + 12 = 112 + 12 = 124°
m ∠UST = 2(28) = 56°

Answer:
m > 3 for 2 solutions.
m = 3 for one solution.
Step-by-step explanation:
mx^2 - 2mx + 3 = 0
For 2 solutions the discriminant b^2 - 4ac > 0 so we have
(-2m)^2 - 4*m* 3 > 0
4m^2 - 12m > 0
4(m^2 - 3m) > 0
m^2 - 3m > 0
m(m - 3) > 0
m > 3 - this is the result for 2 solutions.
For one solution the discriminant = 0
so m(m - 3) = 0
and m = 3 for 1 solution.
