Answer:
r = √98
Step-by-step explanation:
angle A and the diameter form an isosceles right triangle, with OA as the hypotenuse and r as the other sides. You can then make and solve an equation from the Pythagorean Theorem:
r^2 + r^2 = 14^2
2r^2 = 14^2
2r^2 = 196
r^2 = 98
r = √98
Supplementary angles will always add up to 180. If you had a straight line, and you drew another line across that line, the two angles on either side of that line would add up to 180 because a flat line is equal to 180 degrees.
Answer:
Reflection, Translation, and possibly Rotation
Answer:
C
Step-by-step explanation:
1/4+3/4+3/4= 7/4
Now, we need to express as a mixed number.
7/4 = (4+3)/4 = (4/4) + (3/4) = 1 + 3/4 = 1 3/4
Answer C.
