.
Answer:
Exterior angle: <6
Step-by-step explanation:
Exterior angles are the angles outside.
Answer:
x is 6
look at the ratio of 2.1 to 21
2.1 is multiplied by 10 to get 21 and therefore since these fractions are equal, x would have to be 6 in order for the equation to work
Step-by-step explanation:
Answer:
1.
B swap the order of equation
2. yes, they are equivalent and yes, they give same solution
