The tangent at A is perpendicular to OA, so has a slope that is the negative reciprocal of that of the radius: -1/2.5 = -2/5.
The answer is 1/2n-4
Multiplying a number n by 1/2 is the same as dividing that number by 2.
The value of 
.
We know that,
➪ 125° + + 30° = 180°
➪ + 155° = 180°
➪ = 180° - 155°
➪ = 25°
Therefore, the value of is 25°.
Now, the three angles of the triangle are 125°, 25° and 30°.
✒ 125° + 25° + 30° = 180°
✒ 180° = 180°
✒ L. H. S. = R. H. S.
Answer:
10
Step-by-step explanation:
Answer:
x - axis
Step-by-step explanation:
