Question

One angle of a right angled triangle is 36 degree ,find the third angle in grade

Answer 1

$Let \: the \: third \: angle \: be \: x$

$36 + 90 + x = 180$

$106 + x = 180$

$x = 180 - 106$

$x = 74$

$54$

$\huge\underbrace\green {\dag some \ things \ to \ assume :-\dag}$

(according triangle referred in the pic that i have attached )

• Let the right angle (90) at $B \ or \ \angle ABC$

• Let the another angle of 36 at $C \ or \ \angle ACB$

• Let the third angle x or $\angle CAB$

$\huge\underbrace\red{\dag Given:- \dag}$

One angle of a right angled triangle is 36 degree

$\huge\underbrace\pink {\dag To Find:- \dag}$

find the third angle (x or ∠CAB)

$\huge\underbrace\green {\dag Property\:Used:- \dag}$

angle sum property of triangle

$\huge\underbrace\purple{\dag Solution:- \dag}$

In $\triangle ABC$

And the another $\angle \ be \ x\ at \ A \ or \ \angle CAB$

As we know that angle sum of triangle$= 180$

$\angle ABC + \angle ACB + \angle CAB =180$

$90+36+x=180$

$126+x=180$

$x=180-126$ [brining 126 to RHS]

$x=54$

hence third angle $(x\ or \ \angle CAB) \ is \ \boxed{54}$
