Answer:

$x = 10°$

$z = 66°$

Step-by-step explanation:

$(9x - 24)° + (12x - 6)° = 180°\\21x° - 30° = 180° \\ 21 x° = 180° + 30° \\ 21x° = 210° \\ x° = \frac{180°}{30°} \\ x° = 10°$

z° = 9x - 24 ( vertically opposite )

z° = 9(10) - 24

z° = 90 - 24

z° = 66°

Sergeu [11.5K]

Answer:

Perimeter of square Q is 49 inches.

Step-by-step explanation:

Let x be the length of side of square P and y be that of square Q.

It is given in the question that :

$\frac{x}{y}=\frac{2}{7}$

Also it is given that x=3.5 inches.Hence

$\frac{3.5}{y}=\frac{2}{7}$

∴ y=12.25 inches.

Perimeter of square Q is 4y = $4\times12.25=49$ inches.

∠1 and ∠2 are complementary.

Kazeer [188]

If angles are complementary, they add up to 90 whereas when they are supplementary, the add up to 180. So now let's focus on this problem. It says angle 1 and 2 are complementary. Therefore;
angle 1 + angle 2 =90
x+(3x+30)=90
x+3x+30=90
4x+30=90
-30 -30
4x=60
4/4x=60/4
x=15
Therefore, the value of x is 15
