MARK ME AS BRAINLIEST!!! :)

Answer 2

$\huge{\underline{\underline{\boxed{\sf{\red{Aɴsᴡᴇʀ\: ࿐}}}}}}$

Given

In the figure angle =90degree angleA= angleC and bc=10cm then find the value of tan 45 degree

Answer

angle b = 90°

angle a = 30°

angle c = 60° __( remaining angle of triangle )

side opposite to 30° = 1/2 × hypotenuse

BC = 1/2 × AC

= 1/2 × 10

= 5 cm.

side opposite to 60° = √3/2 × hypotenuse

AB = √3/2 × AC

= √3/2 × 10

=5√3 was cm.

Ans. side BC = 4 cm. Side AB = 5√3 cm.
