Answer:
<h2>D. 13</h2>
Step-by-step explanation:
Remember that in a isosceles trapezoid, its angles on the base are always congruent.
Also, we know by definition that the sum of interior angles of a trapezoid is equal to 360°, so
Therefore, the right answer is D.
I think the correct answer from the choices listed above is the distributive postulate. The expression 3x + 3 = 3(x + 1) is an example of a distributive postulate. It <span>says that multiplying a number by a group of numbers added together is the same as doing each multiplication separately. Hope this answers the question.</span>
The sides of the isosceles triangle are two equal legs and the remaining side is called base.
Answer:
B √8
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
The center of the circle is (1, 6).
(x − 1)² + (y − 6)² = r²
The circle passes through the point (-1, 8).
(-1 − 1)² + (8 − 6)² = r²
4 + 4 = r²
r = √8
