Answer:
the cotangent is = cos / sen or 1/ tan
Answer:
y = 5
Step-by-step explanation:
The 3 interior angles of a triangle sum to 180°
Sum the 3 given angles and equate to 180
100 + 4y + 25 + 3y + 20 = 180 ← simplify left side
7y + 145 = 180 ( subtract 145 from both sides )
7y = 35 ( divide both sides by 7 )
y = 5
No. You have to calculate the unit rate by dividing 30 and 6 which is 5. Then 40 divided by 18 which is 2.22 repeating. since they don't equal the same thing, it is false.
0.98, 0.34, 0.27
pretend the zeors/decimals arent there and its the same thing, just remember to out the zeros back in when you write down your final answer
