1-4x
Step-by-step explanation:
Answer:
Solid
Step-by-step explanation:
All of the particles are closely pressed to gather and they are not freely moving around, instead, they are just vibrating. This is what happens in solids, the particles are so close together that objects cannot move through them.
Without figure its not possible. What does this D come from? is it a triangle or quadrilateral or exterior angle? Furnish this information then only it can be solved.
<span>I guess, it is sum of 2 angles. If that is right, 2x + 5x = 91 or 7x =91 or x =13 so 2x = 26. Does that work? </span>
<span>Second is same type I guess! </span>
<span>2x-1 + 5x +2 = 57. So 7x = 56, x = 8. So DBC = 42. </span>
