I believe the answer would be -2 and -11 hope this helped!
Answer:
.
Step-by-step explanation:
6^3 = 216
(-x)^3 = - x^3.
1 = sin²0 + cos²0
sin²0 = 1 - cos²0
sin²0 = 1 - 11/36
sin²0 = 25/36
sin 0 = 5/6 or -5/6
In the first quadrant, the values for sin, cos and tan are positive.
sin0 = 5/6
Answer:
<h3> To find x you need to divide polygon into triangles</h3><h3>The formula
: "the sum of exterior angles=360°" is false for concaved polygons</h3>
Step-by-step explanation:
α = 180° - 135° = 45°
β = 180° - 120° = 60°
γ = 180° - 60° = 120°
δ = 180° - x
ε = 180° - 80° = 100°
If we divide the pentagon into five triangles then:
5•180° = α + β + γ + δ + ε + 4x
900° = 45° + 60° + 120° + x + 100° + 4x
900° = 325° + 5x
5x = 575°
x = 115°
60° + 120° + 135° + 80° + 115° = 510° ≠ 360°
Answer:
The answer to your question is:
Step-by-step explanation:
Data
B = 70°
c = 14
Process
sin Ф = b / c
b = c sinФ
b = 14 sin 70
b = 14 x 0.94
b = 13.16
cos Ф = a/c
a = c x cos Ф
a = 14 cos 70
a = 14 x 0.34
a = 4.76
C = 90° it is a right angle
A = 180 - 90 - 70
A = 180 - 160
A = 20°
