Preeti Dabral 1 year, 8 months ago

Here, a = 6 - √35

{tex}\begin{aligned} & \Rightarrow 1 / a=1 /(6-\sqrt{35}) \\ & \Rightarrow 1 / a=(6+\sqrt{35}) /[(6+\sqrt{35})(6-\sqrt{35})] \end{aligned}{/tex}

[By multiplying (6 + √35) in both numerator & denominator]

{tex}\begin{aligned} & \Rightarrow 1 / a=(6+\sqrt{35}) /\left(6^2-(\sqrt{35})^2\right) \\ & \Rightarrow 1 / a=(6+\sqrt{35})(36-35) \\ & \Rightarrow 1 / a=(6+\sqrt{35}) / 1 \\ & \Rightarrow 1 / a=6+\sqrt{35} \end{aligned}{/tex}

Now we have to find value of a² + 1/a²

{tex}\begin{aligned} & \Rightarrow a^2+1 / a^2=(a)^2+(1 / a)^2 \\ & \Rightarrow(6-\sqrt{ } 35)^2+(6+\sqrt{ } 35)^2 \\ & \Rightarrow\left(6^2-2 \times 6 \sqrt{35}+35\right)+\left(6^2+2 \times 6 \sqrt{35}+35\right) \\ & \Rightarrow 36-12 \sqrt{ } 35+35+36+12 \sqrt{ } 35+35 \\ & \Rightarrow 72+70 \\ & \Rightarrow 142 \end{aligned}{/tex}

ANSWER

In fig., Ab||CD angle APQ= 50°, angle PRD=127° then the value of x and y respectively

Posted by Pushkar Gajbhiye 1 year, 8 months ago

CBSE > Class 09 > Mathematics

1 answers

Preeti Dabral 1 year, 8 months ago

We are given that {tex}AB\parallel CD,\angle APQ = {50^\circ }{/tex} and {tex}\angle{/tex}PRD = 127°
We need to find the value of x and y in the figure.
{tex}\angle{/tex}APQ = x = 50° (Alternate interior angles)
{tex}\angle{/tex}PRD = {tex}\angle{/tex}APR = 127° (Alternate interior angles)
{tex}\angle{/tex}APR = {tex}\angle{/tex}QPR + {tex}\angle{/tex}APQ.
127° = y + 50°
{tex}\Rightarrow{/tex} y = 77°.
Therefore, we can conclude that x = 55° and y = 77°
Alternatively, 127° = y + x (because exterior angle is equal to the sum of interior opposite angles).
so, 127° = y + 50°
which gives, x = 50° and y = 77°
