Question

best answer gets brainliest find the missing angle for all of them and state which one.

Answer 1

Answer:

it get coincidence in each other

Answer 2

Question:-

What is the remaining angle $\angle x$ in each diagram? State which one.

Solution:-

If we find the sum of angles in each diagram we can find the remaining angle. This can be solved by linear equation method.

(1) In the first diagram,

$\rightarrow 48^{\circ}+\angle x=90^{\circ}$

$\rightarrow \angle x=90^{\circ}-48^{\circ}$

$\rightarrow \boxed{\angle x=42^{\circ}}$

(2) In the second diagram,

$\rightarrow 76^{\circ}+\angle x=90^{\circ}$

$\rightarrow \angle x=90^{\circ}-76^{\circ}$

$\rightarrow \boxed{\angle x=14^{\circ}}$

(3) In the third diagram,

$\rightarrow 20^{\circ}+\angle x=180^{\circ}$

$\rightarrow \angle x=180^{\circ}-20^{\circ}$

$\rightarrow \boxed{\angle x=160^{\circ}}$

(4) In the last diagram,

$\rightarrow 83^{\circ}+\angle x=90^{\circ}$

$\rightarrow \angle x=90^{\circ}-83^{\circ}$

$\rightarrow \boxed{\angle x=7^{\circ}}$
