Answer:
96 degrees
Step-by-step explanation:
you have two angles that each measure 42 degrees, giving you 84 degrees combined
there are 180 degrees in a triangle, therefore the vertex angle is equal to 180 minus 84, or 96 degrees
check:
42 + 42 + 96 = 180
180 = 180
Answer:
39
Step-by-step explanation:
the first three call 3, making it 3*3, then each of them will get 3 more, making it 3+(3*3)+(3*3*3),3+9+27, 39
If George's bike weighs 15 pounds, then we can say that because Obed's bike is 3 pounds heavier than George's, Obed's bike weighs 18 pounds. If Obed's bike weighs 18 pounds, then we can say that because Elsa's bike is twice as heavy as Obed's, Elsa's bike weighs 9 pounds.
