CosA=5/13 TanA=12/5

Maahi ......♾ 5 years, 2 months ago

Sin A= 12/13 Therefore p=12 and h=13 b2 = h2-p2 b2= (13)2 -(12)2 b2=169-144 b2=25 b= root25 b=5 Hence cos A= b/h=5/13 tan A=p/b=12/5

Priya ✧*｡٩(๑˙╰╯˙๑)و✧*｡ 5 years, 2 months ago

Given sin A=12/13 ie. Opposite/Hypotenuse Then By Pythagoras theorem AC^2=AB^2+BC^2 13^2=12^2+BC^2 169=144+BC^2 169-144=BC^2 √25=BC 5=BC cos A = Adjacent side/Hypotenuse cos A=5/13 tan A= 12/5

Statement: If a line is drawn parallel to one side of a triangle, to interest the other two sides at indistinct points, the other two sides are divided in the same ratio. Given: - In △ABC,DE∥BC,,,, To prove:- AD/DB = AE/EC,, Construction:- BE and CD are joined. EF⊥AB and DN⊥AL,, are drawn.,, Proof:-,, ar(△ADE) = 1/2×AD×EF,, =1/2×AE×DN,, ar(△BDE) = 1/2×BD×EF,, ar(△CDE) = 1/2×EC×DN,, ar(△ADE)/ar(△BDE) = 1/2×AD×EF/1/2×BD×EF ........(1),, ar(△ADE)/ar(△CDE) = 1/2×AE×DN/1/2×EC×DN ........(2),, But, ar(△BDE) = ar(△CDE) ..............(3),, , as they are on the same base DE and DE∥BC,, from (1), (2) and (3) we get AD/DB = AE/EC,, Thank you.

Yogita Ingle 5 years, 2 months ago

If sinA = 12 / 13 , so find 1 / cos A = ?

sin²A + Cos²A = 1

(12/13)² + cos²A = 1

144/169 + cos²A = 1

cos²A = 1 - 144/169

cos²A = (169-144)/169

cos²A = 25/169

cos A = 5/13

1/cosA = 13/5

ANSWER

There are 6 trigonometrical ratios (sine, cosine, tangent, cotangent, secant and cosecant) and the values ofthese trigonometrical ratios can be calculated for angleslike 0°, 30°, 45°, 60° and 90°by drawing a right angled triangle and an isoscelesright triangle. (See the fig. below) In equilateral triangle, each angle is of 60°, so we can find the values of angles of 30° and 60°. In Isosceles Right Triangle, the value for 45° can be calculated. For 0° and 90° any one of them can be used. In Equilateral Triangle, the length of altitude is x√2 if the side of Equilateral Triangle is x unit. Using above concept, solve questions number 1 and 2 1. Determine the value of x if 2cosec²30° + x.sin²60° - ? ? tan²30° = 10
