Question

in this figure, find x​

Answer 1

In a triangle ABC,

<A+<B+<C=180⁰

40⁰+<B+90⁰=180⁰

<B=180⁰-130⁰=50⁰

In a triangle BED,

<B+<E+<D=180⁰

50⁰+×⁰+100⁰=180⁰

×⁰=180⁰-150⁰=30⁰

Answer 2

Answer:

30°

Step-by-step explanation:

In triangle ABC , The sum of angle is 180°

so, 90°+40°+angle B = 180°

angle B = 180° - 130°

=50°

Now, in triangle BEC

100°+50°+x°=180°

x°=180°-150°

x° =30°

I hope this helps you.
