Answer:
The correct option is 1.
Step-by-step explanation:
Two triangles are called similar if all the corresponding angles are congruent or all corresponding sides are in same proportion.
In triangle MNO and triangle RTS.
(Given)
(Given)
According to the angle sum property, the sum of all interior angles of a triangle is 180 degree. Since two corresponding angles are congruent, therefore third angle is also congruent.

Since all corresponding angles are congruent, therefore the triangles MNO and RTS similar.
The triangle are congruent by AA rule of similarity. Each triangle has two congruent angles, therefore both triangles are similar. Option 1 is correct.
4*12=48
48-28=28
so 4 boxes with 12 gauze so 48 gauze and 28 used so 28 leftist
100 x 88.353
= 10 x 10 x 88.353
= 10 x 883.53
= 8835.3
Eight thousand, eight hundred and thirty five, plus three tenths.
I am assuming that PC is a radius.
d = 2 * PC = 2 * 17 = 34
C = pi * d
C = pi * 34 = 34pi cm
if PC is a diameter, the change the 34 into 17.
