Answer» ong>Step-by-step explanation: answr search What would you like to ask? 10th Maths Real Numbers Revisiting Irrational Numbers Prove that 3 + 2√(5) is irr... MATHS Prove that 3+2 5
is irrational. MEDIUM Share Study later ANSWER Prove 3+2 5
is irrational. → LET take that 3+2 5
is rational number → so, we can write this answer as ⇒3+2 5
= a
Here a & b use two coprime number and b =0. ⇒2 5
= b a
−3 ⇒2 5
= b a−3b
∴ 5
= 2b a−3b
Here a and b are integer so 2b a−3b
is a rational number so 5
should be rational number but 5
is a irrational number so it is contradict - Hence 3+2 5
is irrational. please MARK me as brenalist |

Proof the trigonometric ratios of 45° |
|
Answer» >
Let a rotating LINE OX−→− rotates about O in the anti-clockwise sense and starting from the initial POSITION OX−→− traces out ∠AOB = 45°. Trigonometrical Ratios of 45° 0Save Take a point P on OY−→− and draw \(\overline{PQ} \) perpendicular to OX−→−. Now, ∠OPQ = 180° - ∠POQ - ∠PQO = 180° - 45° - 90° = 45°. Therefore, in the △OPQ we have, ∠QOP = ∠OPQ. Therefore, PQ = OQ = a (say). Now, OP2 = OQ2 + PQ2 OP2 = a2 + a2 OP2 = 2a2 Therefore, OP¯¯¯¯¯¯¯¯ = √2 a (Since, OP¯¯¯¯¯¯¯¯ is POSITIVE) Therefore, from the right-angled △OPQ we get, sin 45° = PQ¯¯¯¯¯¯¯¯OP¯¯¯¯¯¯¯¯=a2√a=12√=2√2 cos 45° = OQ¯¯¯¯¯¯¯¯¯OP¯¯¯¯¯¯¯¯=a2√a=12√=2√2 And tan 45° = PQ¯¯¯¯¯¯¯¯OQ¯¯¯¯¯¯¯¯¯=aa=1. Clearly, CSC 45° = 1sin45° = √2, sec 45° = 1cos45° = √2 And cot 45° = 1tan45° = 1 hope it helps you |

Answer» ong>Answer: ) It is given that line AB is tangent to the circle at A. ∴ ∠CAB = 90º (Tangent at any point of a circle is perpendicular to the RADIUS throught the point of contact) Thus, the measure of ∠CAB is 90º. (2) Distance of point C from AB = 6 cm (Radius of the circle) (3) ∆ABC is a right triangle. CA = 6 cm and AB = 6 cm Using Pythagoras theorem, we have BC2=AB2+CA2⇒BC=62+62−−−−−−√ ⇒BC=62–√ cm Thus, d(B, C) = 62–√ cm |
