Answer:
Yes, letter D is correct.
Step-by-step explanation:
The shape is a trapezoid so you'll have two congruent pairs of base angles.
Answer:17°
Step-by-step explanation:
let them unknown exterior angle be y
Sum of exterior angles =360
51+84+48+27+65+68+y=360
343+y=360
Collect like terms
y=360-343
y=17
There unknown angle y is 17°
Convert the expression
then, multiply the fractions, numerators and denominators separately
and you'll get 10/3, to simplify it'll be 3 1/3 or 3.3333
