Answer:
50°
Step-by-step explanation:
all triangles = 180°
add 53 + 77 = 130
subtract 180 - 130 = 50
giving you your answer of 50°
Answer:
132
Step-by-step explanation:
8×4×3 + 3×3×4
96+36=132
Step-by-step explanation:
<u>Properties used</u>
- logₐ a = 1
- log aᵇ = b log a
- log ab = log a + log b
See the steps below
- - log (4*10⁻³) =
- - (log 4 + log 10⁻³) = (log 4 ≈ 0.6 rounded)
- - (0.6 - 3*log 10) =
- - (0.6 - 3*1) =
- - (0.6 - 3) =
- - (- 2.4) =
- 2.4
Answer:
= - √3/3
Step-by-step explanation:
Tan ( 11π/6)
= Tan ( (12π - 11π)/6)
= Tan ( 2π - π/6)
using Tan ( A - B) = (Tan A - TanB)/(1 + TanATanB)
A = 2π B = π/6
= (Tan 2π - Tan π/6)/( 1 + Tan2π * Tan(π/6)
Tan 2π = 0
=> ( 0 - Tan π/6)/(1 + 0)
= - Tan π/6
Tan π/6 = √3/3
= - √3/3
