Hope this helps.
Answer:
See explanation
Step-by-step explanation:
Connect points A and O and B and O. Consider two right triangles AOE and BOE. In this triangles,
- AO=BO as circle's radii;
- OE is common leg.
By HL theorem, these triangles are congruent, thus, AC=BC.
<span>Acute angle is an angle measure less than 90 degrees
Right angle is an angle that measure 90
degrees
Obtuse angle is an angle that measure more than 90 degrees.
In the given situation, we need to find the value of x of an acute angle with
the given situation
=> (2x-12)
=> 0 < (2x -12) < 90
=> 12 < 2x < 102
=> 6 < x < 51
Let’s check our answer
=> 2 (51- 6)
=> 102 – 12
=> 90
Thus, the value of x = 51 degrees

Answer:
(-12, -20).
Step-by-step explanation:
A dilation of factor 4 moves (-3, 5) to (-3*4, 5*4) = the point (-12, 20).
A reflection over the x-axis is (x, y) ------> ( x, -y).
So ( -12, 20) goes to (-12, -20).
Answer:
5/3
Step-by-step explanation:
z = (Distributed score - Mean)/Standard deviation= (80-70)/6 = 5/3
