Question

find X in the following figure​

Answer 1

Step-by-step explanation:

Given: TS=SR

angle TSR=90

In triangle RST,

angle TRS = angle RTS (Angles opposite to equal sides of a triangle are equal)

angle TRS + angle RTS + angle RST = 180 ( Angle Sum Property of a Triangle)

=angle STR + angle STR + 90 =180

= 2 STR=90

= angle STR= 45

Hence x= 45
