Answer:
the answer is #2-62.5%
Step-by-step explanation:
Distance = 500 miles
Distance of automobile = 10r
r = 50
Distance = 10 x 50 = 500 miles
ans: ii) 87° and iii) 60°
ii)
y° = 180° - ( 56° + 37°)
missing angle on triangle is alternate angle of y° so are equal and sum of angles of triangle is 180°
iii)
x° + 2x° = 180°
sum of co interior angles is 180°
25= r•r•8 ⇔ 25/8 = r²
then
