43.5 is 783 divided by 18 783 ÷ 18 = 43.5
Reason:
2. SD ⊥ HT. ∴ ∠SDH = ∠SDT =90°
3. Given (It is given in the question)
5. RHS congruence
(Here, the right angle, hypotenuse and one side of ΔSHD is congruent to that of ΔSTD).
Statement:
4. Line segment SD = SD
(Reflexive property is used to prove congruence of triangles. This property is used when an angle or line segment is congruent to itself.)
C. It is fifth degree because the highest power in it is 5. It is a binomial because there are two terms in it.
A is also 5th degree, but it has three terms. D is a binomial, but its degree is 3.
B is neither a binomial nor fifth degree.
