Answer:
12.
m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°
13.
Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°

G.M. = √81 * 4
G.M. = √324
G.M. = 18
In short, Your Answer would be 18

Answer:
x = 0
Step-by-step explanation:
Rewrite (6^2)^x =1 as 6^(2x) = 1.
Next, take the logarithm (common or natural) of both sides, obtaining
2x log 6 = log 1
2x log 6 = 0
Then x = 0.
Note that (6^2)^0 = 1, since any positive number raised to the prower 0 is 1.
Sub x^2+12x+10 for y in other equaiton
-8x+x^2+12x+10=10
x^2+4x+10=10
minus 10 both sides
x^2+4x=0
factor
(x+4)(x)=0
set to zer
x+4=0
x=-4
x=0
x=-4 or 0
sub back
y=0^2+12(0)+10, y=10
(0,10)
y=(-4)^2+12(-4)+10, y=-22
(-4,-22)
solutions are
(0,10) and (-4,-22)
