Answer:
Step-by-step explanation:
26. 16m
27. 15m
28. 37 degrees
29. 114 degrees
30. angle I is the only non given but the angles of a triangle add up to 180, so 180 minus the two givens, 114+37, which is 151. subtract 151 from 180 and you get 29. So 29 degrees
Answer:
3.2
Step-by-step explanation:
25/100
because the 1. is more than 25 so it go to 100th
Area of the sector = 90/360 ×πr^2
=1/4 ×3.142×6×6
=1/4×113.112
=28.278kilometers square
Approximately 28kilometers square
Answer:
45°
Step-by-step explanation:
Let's understand "supplement" and "complement" -- basics of geometry of angles.
- When we say two angles, a & b, are supplementary, we mean that both ADD up to 180.
- When we say two angles, a & b, are complementary, we mean that both ADD up to 90.
<em><u>If we have given an angle, such as "x", to find its supplement, we subtract the angle from 180. Similarly, we would need to subtract the angle x from 90 if we were to find the complement of the angle.</u></em>
<em><u /></em>
We want to find complement of 45, so we subtract 45 from 90 to get:
90 - 45 = 45°
Hence, the complement of a 45° angle = 45°
