Answer:
120 degrees

Explanation:
Opposite angles (angles that are on opposite sides of an intersection) are equal to each other. Because angle 2 and 120 degrees are opposite angles, angle 2 is equal to 120 degrees.

Solve the simultaneous equations by substitution 3 x − 7 y = − 10 x = 5 y + 2

mojhsa [17]

Answer:

$3x-7y=-10_{(1)} \\x=5y+2_{(2)}\\$

Substituting Equation 2 into equation 1

$3(5y+2)-7y=-10_{(3)} \\15y+6-7y=-10\\15y-7y+6=-10\\8y+6=-10\\8y=-10-6\\8y=-16\\y=\frac{-16}{8} \\y=-2\\$

Substitute the value of y into Equation 2

$x=5y+2\\x=5(-2)+2\\x=-10+2\\x=-8\\$

Therefore x=-8, y=-2

Answer:

The first answer: 5bk + 5b + k

Step-by-step explanation:

Now, you might say it would be the 10bk one, but that's not right.

The only you can get two variables together is through multiplication. That's why 10bk would not work.
