<h3>★ <u>Solution:</u></h3>
Since it is given that the two angles are supplementary their sum must be equal to 180 degree
6x + 8 + 12x - 8 = 180°
→ 18x = 180°
→ x = 10°
Now substitute the value of x in the given two measures of angles.
- m∠ABC = 6x + 8 = 68°
- m∠DEF = 12x - 8 = 112°
Therefore the 2 angles are <u>68°</u> and <u>112°</u>

Hello,
Answer A
Theorem of Al Kashi gives:
x²=105²+85²-2*105*85*√2/2=5628.14395...
x=75.0209... (mi)
X=3
y=5
You have to cancel out either the x values or the y values (I chose y). You multiply both equations by particular numbers so either the x values or y values can be equal to each other, as well as positive or negative to each other. I multiplied -7y by 4 and 4y by 7, and got -28y and 28y. I then canceled those out. The numbers you multiply by also affects the rest of the equations, so I ended up with 48x=4 and -35x=35. After that, you combine like terms, which results in 13x=39. You divide 13 by both sides and you end up with x=3. To find y, all you have to do is plug in the x value to one of the equations, then solve for y. I resulted in y=5.
Hope this helped ^_^
