Answer:

x = 16

Step-by-step explanation:

The angle vertically opposite (4x - 17) is also (4x - 17) , then

4x - 17 and 8x + 5 are same- side interior angles and sum to 180° , that is

4x - 17 + 8x + 5 = 180

12x - 12 = 180 ( add 12 to both sides )

12x = 192 ( divide both sides by 12 )

x = 16

Answer:

x = 16

Step-by-step explanation:

From the diagram (attached along with answer) ,

∠ABY = 8x + 5

∠ZYQ = 4x - 17

∠ABY = ∠XYQ = 8x + 5 (∵ Corresponding angles are equal)

∠XYQ + ∠ZYQ = 180° (∵ Linear pair)

$=> 8x + 5 + 4x - 17 = 180$

$=> 12x - 12 = 180$

$=> 12x = 180 + 12 = 192$

$=> x = \frac{168}{12} = 16$

What is the differences between Mathematics and Science

miss Akunina [59]

I’m not sure if you’re looking for a specific answer, but on a broad spectrum science is typically just applied mathematics. Math can be incorporated into all sciences, especially physics. On occasion, science can also be included in math, like when using derivatives to find the acceleration of a moving object. All in all though, the two subject are very connected.
