Answer:
a = 180 - b + c
Step-by-step explanation:
a + b - c = 180
Move b by subtracting b from both sides.
a - c = 180 - b
Move c by adding c to both sides.
a = 180 - b + c
Therefore a equals 180 - b + c.
Answer:
x = 18
Step-by-step explanation:
5/6x = 15
Multiply each side by 6/5 to isolate x
6/5 * 5/6 x = 15 *6/5
x = 15/5 *6
x =3*6
x = 18
0.4 -> 4/10 (divided by 2) -> 2/5
0.35 -> 35/100 (divided by 5) -> 7/20
we can conclude that the measure of a negative angle coterminal with 4л/3 is B = -2л/3
<h3>How to find the coterminal angle?</h3>
For a given angle A, we define the family of coterminal angles as:
B = A + n*2л
Where n is an integer number.
In this case, we want to find a negative coterminal angle to A = (4л/3), then we can replace it in the above formula to get:
B = 4л/3 + n*2л
Now we just need to find a value of n such that B is negative, if we select n = -1, then:
B = 4л/3 - 2л = 4л/3 - 6л/3 = -2л/3
Then we can conclude that the measure of a negative angle coterminal with 4л/3 is B = -2л/3.
