<u>Proof</u><u> </u><u>:</u><u>-</u><u> </u>
Here we are required to prove that ,
And here it's given that , y || z . Therefore ,
- ∠3 = ∠6 ( alternate interior angles )
- ∠1 = ∠5 ( alternate interior angles )
Now we know that the measure of a straight line is 180°. Therefore ,
Hence Proved !
Answer:
0.206897
Step-by-step explanation:
it is 0.206897 because you have take the whole make uneven fraction an add it to 60 in 60/72 to get 348 divided equals 0.206897
Answer:
(-2,8)
Step-by-step explanation:
-7x-2y = -2
-6x+8y = 76
Multiply the first equation by 4 to eliminate y
-28x -8y = -8
Then add it to the second equation
-28x -8y = -8
-6x+8y = 76
--------------------
-34x = 68
Divide by -34
-34x/-34 = 68/-34
x = -2
Now substitute back into one of the equations to find y
-6x +8y = 76
-6(-2) +8y = 76
12+8y = 76
Subtract 12 from each side
12+8y-12 = 76-12
8y = 64
Divide each side by 8
8y/8 = 64/6
y=8
(-2,8)
