Answer:
86.7
Step-by-step explanation:
L x W = 5.1 x 5.1 = 26.01
B x H ÷ 2 = 5.1 x 5.95÷2 = 15.1725
15.1725 x 4 = 60.69
60.69 + 26.01 = 86.7
The angle subtended by a diameter is a right angle. That's Thales' Theorem (one of them anyway), sometimes thought to be the first theorem of geometry.
So the first choice is true.
The other angles are complementary, not necessarily congruent.
The sides and arcs aren't necessarily congruent either
Answer: first choice
Answer:
26
Step-by-step explanation:
2(5+8)
=2×(13)
=26
therefore 26 is the answer
Answer:
Segment AB is 10 units long.
Step-by-step explanation:
When a segment is bisected, it is divided into two segments of equivalent lengths. Because segment AB is bisected by point M it creates a line somewhat like this.
A --------------------M----------------------B
Thus, if segment Am is 5 units, because segment AM is congruent to BM, segment BM is 5 units as well. Thus, because AM + BM = AB, AB = 10 units.
Divide 7 and 217 and you have 31 so there are 31 pens in each case
