Pi radians =180 degrees:
<span>That is, π rad = 180°
</span>
60° in radian measure = 60° × π / 180°
60° × π / 180° = 1/3 π rad
= 0.33333333333π rad
=
1.0471975512 rad
Answer:
- 9
Step-by-step explanation:
Substitute x = - 3 into the expression
(- 3)² - 2(- 3) - 24
= 9 + 6 - 24
= 15 - 24
= - 9
Now, notice the "tickmarks" on the angles, that means those two angles are equal, now if ∡ABC is 110, then the remaining is 70, 180 - 110, and if you subtract the 70 from 110, what's left is ∡DBC.
