Step-by-step explanation:
okay I think you can solve this question now ☺️
Assuming x is really x^3;
∛729 = 9
The differences of cube rule states: x³-y³= (x-y)(x²+xy+y²)
(x)³-(9)³=(x-9)(x²+9x+9²)
=(x-9)(x²+9x+81)
Hope I helped :)
Answer:
<h2>C. SSS</h2>
Step-by-step explanation:
Since we are not given any angle measure and three side measure, we can prove these triangles congruent by SSS.
Without further information, you can't deduce the length of one side of a triangle knowing the other two.
You can only use the inequalities that tell you that the sum of two sides is greater than the remaining one to get
which is true for all positive x values
So, knowing only the length of two of the sides, we can only say that the third side is between 3 and 35 inches long.
Answer:
52°
Step-by-step explanation:
Angle AOB is the a.pex angle of the isosceles triangle AOB.* Then angles at A and B are congruent and each is the complement of half the angle at O:
∠OAB = 90° -(1/2)(76°) = 90° -38°
∠OAB = 52°
_____
* You know ΔAOB is isosceles because OA and OB are both radii of the circle, hence the same length.
