Answer:
Solution given:
9x-4=8+7x[Vertically opposite angle]
9x-7x=8+4
2x=12
x=12/2
x=6
:.<u>8</u><u>+</u><u>7</u><u>x</u><u>=</u><u>8</u><u>+</u><u>7</u><u>×</u><u>6</u><u>=</u><u>5</u><u>0</u><u>°</u>
Answer:
a=-5,b=3c=-8 d=?
Step-by-step explanation:
4.133 kilometers
2.063 + 2.07 = 4.133
Let x and y represent angles 1 and 2, respectively. The given relations tell you
... x + y = 180 . . . . the sum of measures of a linear pair is 180°
... y = 2x + 6 . . . . angle 2 is 6 more than twice angle 1
One way to solve these is to add twice the first equation to the second.
... 2(x + y) + (y) = 2(180) + (2x +6)
Now, subtract 2x
... 3y = 366
... y = 122 . . . . divide by the coefficient of y
The measure of angle 2 is 122°.
