Answer:
87°
Step-by-step explanation:
If a quadrilateral is inscribed in a circle, then opposite angles are supplementary. That means that z + 93 = 180 and z = 87°
Answer:
(x - 3)² + (y + 5)² = 10
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (3, - 5 ) , then
(x - 3)² + (y - (- 5) )² = r² , that is
(x - 3)² + (y + 5)² = r²
r is the distance from the centre to a point on the line
Calculate r using the distance formula
r =
with (x₁, y₁ ) = (3, - 5) and (x₂, y₂ ) = (6, - 4)
r =
=
=
= ⇒ r² = ( )² = 10
(x - 3)² + (y + 5)² = 10 ← equation of circle
Answer:
the answer is 1649
Step-by-step explanation:
Find the number in the whole number place 8 and look one place to the right for the rounding digit on the right side of the decimal point 5.Round up if this number is greater than or equal to 5 and round down if it is less than 5.
1649
hope i helped and have a wonderful day
The car speed measurements that represent the same level of accuracy compared to the speed limit sign is 64mph (option D).
<h3>What is accuracy?</h3>
Accuracy is the exact conformity to truth or the degree of conformity of a measure to a true or standard value.
Accuracy is different from precision as precision deals with the closeness of an observed value with a true value.
According to this question, a highway sign shows a speed limit of 65 miles per hour. This suggests that a car speed measurement that will represent the same level of accuracy compared to the speed limit sign is 64mph.
64mph is the closest speed measurement to 65mph that does not exceed this speed limit. However, 66 mph is also close but exceeds the true value for the speed limit.

True, for a contrapositive you switch the parts and then make them opposite, but the statement is still true.
