Question

Please explain 3rd and the 4th one !
please explain it to me!​

Answer 1

Answer:

Step-by-step explanation:

A) the third one is simply a regular hexagon

so as there is a formula to calculate the total angles of regular polygons which is

(n-2)*180 where n is the number of sides

you will get 720 in case of hexagon when u substitute the formula

divide 720/6               (6 is no. of sides in a hexagon)

u will get 120 == x

B) sum of interior angles of a quadrilateral is 360

see u might have not noted down the exterior angle which is given

here in this case it's 90 degrees

so interior=180-90=90 degrees

at last lets find x,,

85+70+90+x = 360

x=360-245

x=115 degrees
