in quadrilateral mnop, ∠m ≅ ∠n. quadrilateral mnop could be a:

i. trapezoid ii. rhombus iii. parallelogram

a) iii only

b) ii or iii

c) i, ii, or iii

d) i or ii

C

because a quarteratrall is a shape with 4 sides a rhombus has 4 sides a trapezoidal has 4 sides and a paralleagram two be a shape it has to have four sides or else it wont be a parallel

step-by-step explanation:

20 - 8.47 = 11.53. take away the money he used for lunch from the starting amount of 20.

hope it you

step-by-step explanation:

sin(7pi/6 - pi/3)  

= sin(7pi/6 - 2pi/6)  

= sin(5pi/6)  

= sin(pi - pi/6)  

= sin(pi/6)  

= 1/2  

sin 7pi/6 - sin pi/3  

= sin (pi + pi/6) - sin pi/3  

= -sin pi/6 - sin pi/3  

= -1/2 - sqrt(3)/2  

= -(1+sqrt(3))2
