Answer:

14. x = 1

16. x = 4

18. x = 10

Step-by-step explanation:

14. We have ∠ HGF = ∠ HGP + ∠ PGF

Given, ∠ HGF = 177x + 1, ∠HGP = 1 + 99x and ∠ PGF = 78°

So, 177x + 1 = 1 + 99x + 78

⇒ 78x = 78

⇒ x = 1 (Answer)

16. We have ∠ BCD = ∠ BCK + ∠ KCD

Given that, ∠ BCK = 9x - 2, ∠ BCD = 174° and ∠ KCD = 34x + 4

So, 174 = 9x - 2 + 34x + 4 = 43 x + 2

⇒ 43x = 172

⇒ x = 4 (Answer)

18. We have ∠ IJK = ∠ IJR + ∠ RJK

Now, given that, ∠ RJK = 8x + 10, ∠ IJR = 5x +8 and ∠ IJK = 148°

So, 148 = 5x + 8 + 8x + 10 =13x + 18

⇒ 13x = 130

⇒ x = 10 (Answer)

Write the equation of a line perpendicular to y= -1/3x + 5 and passes through the point (6, 4).
Levart [38]

Answer:

y = 3x - 14

Step-by-step explanation:

Perpendicular lines will have a opposite reciprocal slope, so the slope will be 3.

Plug in the slope and given point into y = mx + b, then solve for b:

y = mx + b

4 = 3(6) + b

4 = 18 + b

-14 = b

Plug in the slope and y intercept into y = mx + b

y = 3x - 14

So, the equation of the line is y = 3x - 14

Answer:

126 inches

Step-by-step explanation:

If your drawing is on a 1 : 40 scale, to find the scale's height, divide the ride's height by 40.

420 / 40 = 10.5

So the drawing will be 10.5 feet tall.

To convert 10.5 feet to inches, multiply it by 12.

10.5 * 12 = 126 inches
