Answer:
40°, 95°, 105°, and 160°
Step-by-step explanation:
Let the smallest angle be x.
Measures of the 3 angles can be expressed as:
The sum of all angles in a quadrilateral = 360°.
Therefore, 
Solve for x
The smallest angle = 40°
Plug in the value of x in the earlier stated expressions to find the measure of the other angles:
Answer:
you need to type the questions out we have no idea what questions there are.
Step-by-step explanation:
Answer:
-1
Step-by-step explanation:
Square root 1 is 1. Add that to the 12 to get 13. Subtract 13 from both sides to get: -5x = 5. Divide both sides by -5 to get your answer: -1
This is a difference of squares, meaning that when you multiply the binomials it would be the front term squared minus the last term squared.
The front term squared = (3A) squared = 9A squared
The last term squared = (4B) squared = 16B squared
Final Answer: D. 9A squared - 16B squared
