Hi,
All you have to do is to use Thales 's theorem.
See picture jointed
10^-1 = 0.1 (10/1 flipped to 1/10)
10^-5 = 10^(-1 x 5) = (1/10)^5
= 1/10 x 1/10 x 1/10 x 1/10 x 1/10
= 1/100 x 1/100 x 1/10
= 1/100000
= 0.00001
What is the decimal I might be able to figure it out
Answer:
∠3=140°
Step-by-step explanation:
∠4 = 40°
∠3 + ∠4 = 180° (co-exterior angles are equal)
∠3 + 40° = 180°
∠3 = 180° - 40°
∠3 = 140°
∠2 = ∠4 = 40° (corresponding angles)
∠3 + ∠2 = 180° (linear pair)
∠3 + 40° = 180°
∠3 = 180° - 40°
∠3 = 140°
hope you understood
