Question

If the two angles of a triangle vare 65° and 35° ,find the third angle of the triangle . What type of triangle is it?​

Answer 1

Answer:

Sum of all angles of a triangle= 180°

65+35+x = 180°

(65+35)= 100

x = 180-100

= 80°

So the measure of third angle is 80°.

This is a acute angles triangle or scalene triangle.

Answer 2

$\mathfrak{\purple{\huge{SolutioN!!}}}$

$\sf{\blue{We\:know\:that\:the\:sum\:of\:all\:angles\:in\:a\:triangle\:is\:180{\degree}}}$

$\sf{Hence,{\angle{ABC} + {\angle{BAC} + {\angle{ACB} = 180{\degree}}}}}$

$\sf{ = > 35{\degree} + 65{\degree} + {\angle{ACB} = 180{\degree}}}$

$\sf{ = > {\angle{ACB} = 80{\degree}}}$

In triangle ABC , all angles are unequal,so all side will also be unequal.

Hence,triangle ABC is a scalene triangle.

Hope this helps!!
