Question

Help me to answer this question... ​

Answer 1

(i)m=45degree

(ii)<RPS=45degree

Explanation:

(i)a triangle=180degree

2m+90=180

2m=180-90

m=90÷2

m=45degree

(ii)<RPS is a triangle same with triangle PST and triangle PQR

<RPS=(180-90)÷2

<RPS=45degree

Answer 2

m=45

RPS =45

Explanation:

the sum of angles of triangle=180 degrees

90+45+m=180

triangle PST is the image of triangle PQR

m=180-135=45 degrees

Angle RPS = 45 degrees ( two angles are adjacent when they have common side, ad do not overlap )
