Answer:
22.5 cm, 30 cm, 37.5 cm
Step-by-step explanation:
Sum the parts of the ratio, 3 + 4 + 5 = 12 parts
Divide the perimeter by 12 to find the value of one part of the ratio.
90 cm ÷ 12 = 7.5 cm ← value of 1 part of the ratio, thus
3 parts = 3 × 7.5 cm = 22.5 cm
4 parts = 4 × 7.5 cm = 30 cm
5 parts = 5 × 7.5 cm = 37.5 cm
The 3 sides are 22.5 cm, 30 cm and 37.5 cm
Answer:
2) ∠SDH and ∠SDT are right angles because SD ⊥ HT.
3)
as it is given in the question.
4)
is the reflexive property.
5) ΔSHD ≅ ΔSTD by RHS congruency.
Step-by-step explanation:
Given in the question:

In ΔSHD and ΔSTD
(Given)
(SD ⊥ HT)
(Common)
Therefore,
(By RHS rule)
Reflexive property of congruency is defined as the property in which something is equal to itself. Hence, the reflexive property of these two triangles is 
Ones and tens thats the anwers
For this case we have to by definition:
1 kg equals 1000 grams
Shark 1:
405 kg and 68 grams

Thus, shark 1 weighs 405,068 grams.
Shark 2:
324 kg and 75 grams

Thus, shark 2 weighs 324,075 grams.
Subtracting we have:

Thus, shark 1 weighs 80,993 grams more than the second.
Answer:
Shark 1 weighs 80,993 grams more than the second.
