Multiplying ratios is just like multiplying fractions.
Ex:
5:10 = 5/10
5:10 · 2:20 = 5/10·2/20.
keep 5/10,
simplify 2/20 to 1/10,
multiply 5·1, and 10·10, and the answer is 5/100 or .05

Step-by-step explanation:
Answer:
None of these lines are parallel, so the congruent angles are vertical angles. 4 and 2 are vertical, thus they are congruent.
Step-by-step explanation:
Answer:
30.
Step-by-step explanation:
The total degree of a triangle is 180.
They give you 60.
The center line coming down creates a 90 degree angle.
So 60+90=150.
180-150=30.
So the top angle is 30 degrees on both sides.
Uh, 1108 + 6(150+6-16), so K = 1948. There was no pretext to this so I used my boyfriend as an example.
