1a. A regular polygon has 10sides. i)Name the polygon.
ii)How many triangles can be obtained from this polygon if cut into triangles.
iii)Find the sum of its interior angles.
iv)A polygon which has n sides is cut into triangles, write formula to find the sum of its interior angles in terms of n.

b)A student cycles 3km east from A to B and then 4km to C. Find the distance and bearing from C from A. scale: 1cm to 1km. tan60° =1.7.

2a. Find the height h, of the building if the scale is 1cm to 10km.

b)Find x, 2x and 3x from the diagram below.
2x+ 3x +82°+128°= 360°.Copy and complete.

answer: sorry but i need points

step-by-step explanation:

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265

connie < felicia < stew

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
