Answer:
Step-by-step explanation:
Opposite angles of an inscribed quadrilateral are supplementary, so ...
m∠A + m∠C = 180°
Substituting the given expressions, we have ...
(3x +6)° + (x+2)° = 180°
4x +8 = 180 . . . . . . collect terms, divide by °
x +2 = 45 . . . . . . . . divide by 4
3x +6 = 135 . . . . . . multiply by 3
This is the value of angle A in degrees, so ...
m∠A = 135°
is the required equation.
<u>Step-by-step explanation:</u>
Equation of line is given as, -2x + 3y = 15
Now we have to write the equation in y = mx+ b form, where m is the slope and b is the y- intercept.
So the above line can be written as,
3y = 2x+ 15
Dividing both sides by 3 we will get,
is the equation of the given line
If a line is parallel to the given line then its slope must be the same, so the equation of line parallel to the given line is,
is the required equation.
