Answer:
0.5, pi/2, square root of 4, and im assuming you meant to put 3.4 for the first number so that is the greatest number.
Step-by-step explanation:
set 0.5 and 3.4 aside since they are normal numbers. the square root of 4 is 2 since 2 squared = 4. to figure out pi/2, divide 3.14 by 2 (3.14 is pi) which is 1.57.
Answer:
x = 25
Step-by-step explanation:
The measure of an inscribed angle in a circle is half the measure of the arc it subtends. The acute angles in a right triangle are complementary.
__
Inscribed angle CAD is half the measure of arc CD, so is 80°/2 = 40°.
Acute angle 2x° is the complement of angle CAD in the right triangle shown, so we have ...
2x° = 90° -40° = 50°
x = 25 . . . . . . . . . . . . divide by 2°
