Answer:
A. 
Step-by-step explanation:
According to tangent theorem, a tangent is formed when the radius of a circle is perpendicular to the line, meeting at a point around the circle, such that the tangent line would be perpendicular to the radius of the circle with a center.
Given that 
is a tangent of the circle O, at a point C, and 
is a radius, therefore, it follows that:
.
This means the radius of the circle is perpendicular to the tangent formed at point C.
It is d. The h is the amount of hours and this must be paired with 25 because that is the rate do you can eliminate b and c. It is not a because that is making it so the cost is above 200 when you are trying to keep it below that
So do 260+570 which is 830
The real sum is 823

Answer:
A) 220.5 mm^2
Step-by-step explanation:
<u>Explanation</u>:-
Given A regular triangular pyramid has a base of area is 31.5mm^2
and also given surface area of triangular pyramid is 252 mm ^2
by using formula
surface area of regular triangular pyramid = base of area + half of lateral surface.
252 = 31.5 + 
220.5 = lateral area of triangular pyramid
lateral area of triangular pyramid = 220.5 mm^2
