Mathematics
1 answer:
kipiarov [429]3 years ago

Answer:

Intersect: (4 4/7 , 2 6/7)

Step-by-step explanation:

A: slope (m)= (-10-8) / (-9 - 10) = 18/19

Equation: y-8 = 18/19 * (x-10)

18x -19y = 28      (1)

B: slope (m) = (12 - -2) / (0 - 7) = -2

equation: y-12 = -2 *(x - 0)

2x + y = 12

38x + 19y = 228      (2)

(2) + (1): 56x = 256            x = 4 4/7

y = 12 - 2x = 12 - 64/7 = 2 6/7

In the figure below line DE is parallel to line FG and transversal AG
Arturiano [62]

Answer: The answer is 147° and 33°.

Step-by-step explanation:  We are given a figure in which the line DE is parallel to the line FG and AG is a tranversal. We are to find the value of 'x' and 'y' from the figure.

Also, given that

∠ABE = (5y - 18)°.

We can see from the figure that ∠DBG and ∠ABE are vertically opposite angles, so they must be equal.

That is,

\angle DBG=\angle ABE\\\\\Rightarrow x=5y-18\\\\\Rightarrow 5y-x=18.~~~~~~~~~~~~~~~(i)

Also, since ∠DBG and ∠FGB are interior angles on the same side of the transversal, so their sum is 180°.

That is

\angle DBG+\angle FGB=180^\circ\\\\\Rightarrow x+y=180.~~~~~~~~~~~~~~~~~(ii)

Adding equations (i) and (ii), we get

y+5y=18+180\\\\\Rightarrow 6y=198\\\\\Rightarrow y=33,

and from equation (ii), we get

x=180-33=147.

Thus, x° = 147° and y° = 33°.
