Answer:
120°; 240°
Step-by-step explanation:
Let's first solve for 
: 
At this point it's just a matter of drawing a circle, and mark where the angle is(please excuse my paint skills, but free hand drawing would be even worse). Red line, is 
on the cosines, and both the green and blue lines are valid solutions. The green line is a quarter of a circle, plus 30°, or 120°. The blue one is 3/4 of a circle, minus 30 degrees, or 240°.
Answer:
3.4567
3.4568
Step-by-step explanation:
We need to find a number between 3.456 and 3.457. In order to do so, we need to dive deeper into the decimal to get numbers in-between.
We need to dive to the ten-thousandths place to get numbers between the two.
Answer:
75
Step-by-step explanation:
Four scores.... add them together and divide by four
(90 + 80 + 70 + 60) / 4 = 75
From angle bisector theorem, we know that:
Moreover:
so:
and
