Answer:
228
Step-by-step explanation:
19 times 12 =228
Answer:
52
Step-by-step explanation:
the answer is 52 because all the angles have to add up to 360 and 128+126+54=308 and 360-308=52
Answer:
Recursive
Explicit
Step-by-step explanation:
An arithmetic sequence an be represented by a recursive rule which gives the first term and defines the nth term by relating it to the previous term, or by an explicit rule which defines the nth term as a function of n.
The recursive rule is that we have the initial term. To find the subsequent term, we will take that <em>previous term</em> and add it to our common difference.
Hence, we are <em>relating the previous terms</em> to define the nth term.
For the explicit rule, we simply have a function of n. To find the nth term, we can substitute our desired term n for n and evaluate.
Answer:
The angle for the top of the triangle is 79. For the right corner would be 56. Then going to the bottom of the blue triangle vertice would be 75. The missing angle next to that one would be 55/
Step-by-step explanation:
Distribute on the left
-4x+6=2x
Get x onto one side. Add 4x to both sides
6=6x
Divide both sides by 6
1=x
Final answer: x=1
