A is the answer half Irish die f Russian stuff right stuff he taught
Step-by-step explanation:
10/94+641=68000
Consider angle XZY in the attached figure. It is always 1/2 the measure of arc XY, no matter where Z may be located on the major arc XZY. This is true even when ZY is very short.
Now, consider what happens when Z falls on top of tangent point Y. The angle is still half the measure of arc XY, still 62°.
Selection C is appropriate.
_____
I apologize for any confusion caused by my choice of Z as the name of the point I added. Nothing in my explanation is intended to refer to the Z already shown in the unmodified figure.
Answer:
42
Step-by-step explanation:
Since the scale factor is 2:7, you can divide the given number by 2 then multiply it by 7, so 12/2x7=42
Answer:
I’m not 100% sure but I think 120°.
Step-by-step explanation:
This is because, angles on a straight line add up to 180°. Because there is 60 degrees on one side of line B, this means the other section is 120° (120°+60°=180°) The angle labelled (3x) is alternate to the angle of 120°. Alternate angles are always equal, meaning that 3x is equal to 120°.
I hope this is right.
Answer:
Complementary angles are two angles that add up to 90°.
For this, we need to know what the value of a is. If you have this value, plug it into this equation:
90 - 3a = measure of complementary angle
For example, if a = 20:
90 - 3(20) = x
90 - 60 = x
30° = measure of complementary angle
