Me so
i will you if you

4.50 · 10 to the 9th power km

5.79 · 10 to the 7th power km

1.50 · 10 to the 8th power km

1.08 · 10 to the 8th power km

7.79 · 10 to the 8th power km

2.79 · 10 to the ninth power km

2.28 · 10 to the 8th power km

Move decimal point one position to the right for each power you move down.
4.5 . 10 = 45.0 . 9 = 450 . 8 etc

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct

They are somewhat similar
