Answer:
m∠1 = 39.5°
m∠2 = 39.5°
m∠3 = 50.5°
m∠4 = 50.5°
Step-by-step explanation:
m∠1 = 39.5° (Given)
m∠2 = m∠1 = 39.5° (∠1 ≅ ∠2)
m∠3 = 90° - 39.5° = 50.5° (∠1 and ∠3 are complementary)
m∠4 = m∠3 = 50.5° (∠1 ≅ ∠2, ∠2 and ∠4 are complementary)
1/2*4=2
She walks 2 miles per hour
BIDMAS so do the 7+3 first = 10
[10 x 5 - 4] (divided by) (2+3)
then work out both brackets by doing the multiplication first
[10 x 5 - 4] = [50 - 4] = 46
(2 + 3) = 5
46 divided by 5 = 9.2
