Answer:
c
Step-by-step explanation:
21×43
=(20+1)×(40+3)
=800+40+60+3
225 minutes
45 min = 20% = 20/100
20 x 5 = 100
45 x 5 = 225
Pi R square
so 36*3.14= 113.4
= 110in Square
the equation is (9), 1,3
angle ABC is 48⁰
angle BCD will be 111⁰ it will be equal to DAB.
111+111+90=312⁰
kite is a quadrilateral so its angles add up to 360⁰
360-312=48⁰
