solve the following questions​

Answer 1

Answer:

$\huge{\underline{\color{teal}{\textsf{\textbf{~~~Answer}}}}}$

figure 1:-

we know that sum of all angles in Triangle is 180° so ,

60° + 70° + x° = 180°

130° + x° = 180°

x = 180° - 130°

x = 50°

thus , the value of x is 50°

figure 2:-

here 50° and the other side are vertically opposite

so the other side = 50°

now, we know that sum of all angles in triangle is 180°

50° + 30° + x° = 180°

80° + x° = 180°

x° = 180° - 80°

x = 100°

thus , the value of x is 100°

Answer 2

$\sf \bf {\boxed {\mathbb {GIVEN}}}$

THe sum of measure of all angles of triangles is 180°

• In first image measure of two angle is given
• let the first angle is 70° and second be 60° and another be x°

$\sf \bf {\boxed {\mathbb {TO\:FIND}}}$

value of X

$60°+70°+x= 180°$

$130° x = 180°$

$Therefore \: X \\ \\ = 180° - 130°$

$=50°$

$Therefore \: value \: \\ \\ of \: X \: is =50°$

Similary we can find the other

And we get the value of X as 100°
