Question

95 The three angle of triangle are in
ratio 1:2:1 @ Find all the angle
of triangles dated​

Answer 1

Answer:

$\sf \pink{Let}$

$\sf \purple{ABC \:be \:the\: D}$

$\sf \blue{Let \:∠A=x}$

$\sf \blue \implies \green{∠B=2x}$

$\sf \red \implies \orange {∠C=x}$

$\sf \purple {∠A+∠B+∠C=180}$

$\sf \green \implies \blue {4x=180}$

$\sf \orange \implies \red {x=45}$

$\sf \purple \therefore \pink {∠A=45}$

$\sf \blue {∠B=90}$

$\sf \red{∠C=45}$

$\sf \purple{Since\: ∠A=∠C}$

$\sf \orange{ABC\: is \:isosceles \:D4}$

$\sf \green{Since \:∠B=90}$

$\sf \pink {ABC \:is \:Right \:angled \:at\: B.}$

Answer 2

Answer:

$\sf \green \implies \blue {4x=180}$

$\sf \orange \implies \red {x=45}$

$\sf \purple \therefore \pink {∠A=45}$

$\sf \blue {∠B=90}$
