Answer:
a = 4
Step-by-step explanation:
Ez, I did it where 6a - 3a which is just 3a and added the 21 to the other side. So now it is 12 = 3a which is simply 4.
The answer according to me would be B (-a) + b
Because when you solve it. It would turn into a - b
The value of 1 raised to any exponent would be 1 because no matter how many times you multiply 1 and 1, it will still be one. So 1 to the power of 200 would be one because you are multiplying 1 two-hundred times.
Final Answer: The answer would be one
Since this is a right triangle, we can use the Pythagorean Theorem, which states a² + b² = c² in a right triangle.
Plugging our numbers in, we get:
(12)² + (35)² = c²
From there, we can square the numbers.
(144) + (1225) = c²
Then, we can add them together to find the sum;
(1369) = c²
And finally, we can find the square root of both sides.
(37) = c
Therefore, 37 is the answer and your answer choice is correct.
Anyway
2pi radians=360
so
-4pi/9radians=xdegrees
2pi/360=-4pi/9r/x
times both sides by 360x
2xpi=-1440pi/9
2xpi=-160pi
divide both sides by 2pi
x=-80
80 degres
