Equation with angles can some please answer

Mathematics
1 answer:
Gelneren [198K]2 years ago
5 0

Answer:

Step-by-step explanation:

Parallel lines. A & B are corresponding angles and corresponding angles are equal.

∠A = ∠B

8x - 8 = 5x + 25

Add 8 to both sides

8x - 8 + 8 = 5x + 25 + 8

8x = 5x + 33

Subtract 5x from both sides

8x - 5x = 5x +33 - 5x

3x = 33

Divide both sides by 3

3x/3 = 33/3

x = 11

∠B = 5x + 25 = 5*11 + 25 = 55 +25 = 80

∠B = 80°

my method
let projection of b onto line dq be M
BM is 2r
then let the remaining angle ( right) be K
in triangle BMK ,
MK = 29-5-r
By Pyth. theorem ,
23^2 = (2r)^2+(29-5-r)^2
529=4r^2+576-48r+r^2
5r^2-48r+47=0
r = 8.493237063 or 1.106762937(rejected)

(x-4)*(x-9)=0 what is x
Strike441 [17]

Answer:

x either equals to 4 of 9 so you can write it like x=4, 9

Step-by-step explanation:

Start by simplifying each sides of the equation.

x^2-13x+36=0

Then factor the left side of the equation.

(x-4)(x-9)=0

Set factors equal to 0

x-4=0 or x-9=0

x=4 or x=9
