Answer:
154.94 cm so pick the third answer.
Step-by-step explanation:
5*12+1=61 total inches.
61*2.54=154.94 cm
The scale factor of the dilation is 2
Answer:
A
Step-by-step explanation:
The triangle shown has all 3 sides equal in length, hence it is an equilateral triangle.
A property of equilateral triangles is the angles are congruent.
The sum of the 3 angles = 180°, hence the measure of each angle is
= 60° → A
The answer is B(11, 2sqrt(12) )
proof
the main equation of the circle is (x-x1)²+(y-y1)²=R²
where C(x1, y1) is the center
so if the center is the origin, it is O(0,0), and the equation becomes
<span> (x)²+(y)²=R²
</span>and the circle passes through the point (-5,2) so we can write
(-5)²+12²=R², it implies R= sqrt(25+144)=sqrt(169)=13
and for <span>B(11, 2sqrt(12) ) </span>11²+ (2sqrt(12))²= 121 + 48= 169= 13
it is checked.
