Answer:
A
Step-by-step explanation:
First, you take base*base*height. Therefore;
A= a+b/2h
= 1.9+3.7/2 * 0.9 = 2.52
Hope this helped!
<span> (3a2 + b) • (3a2 - b) would be ur answer x</span>
The answer would be A. it would be the same either way
Answer:
Step-by-step explanation:
The relevant relations are ...
- an arc has the same measure as the central angle it subtends
- angles of a linear pair are supplementary (total 180°)
- an inscribed angle has half the measure of the arc it subtends
- the total of arcs of a circle is 360°; of a semicircle, 180°
__
arc CB has the measure of central angle COB: 64°
angle AOC is the supplement of angle COB: 180° -64° = 116°
arc AD is twice the measure of inscribed angle ABD: 2×13° = 26°
arc DFB is the supplement of arc AD: 180° -26° = 154°
angle CDB is half the measure of arc CB: 64°/2 = 32°
