Asecant and a tangent meet at a 90° angle outside the circle. what must be the difference between the measures of the intercepted arcs?
a. 45°
b. 90°
c. 180°
d. 270°

answer: c. 180°

step-by-step explanation:

since, when the secant line and tangent line of a circle intersect outside the circle then the angle formed by their intersection is   half of the positive difference of the intersected arcs,

here, a secant and a tangent meet at a 90° angle outside the circle.

thus,

⇒ option c is correct.

plants store their excess carbohydrate in the form of starch so that it could be used as energy source later on. the excess carbohydrate is converted into starch in the plastid i.e. chloroplast & this process occurs in the presence of sunlight. it is an insoluble polymer of glucose which gets stored in cell organelles named as amyloplasts. in some plants, starch is also stored in roots and embryos.
