Find the missing side of each triangle.
Answers
Answer:
x = 2√5
Step-by-step explanation:
Using the Pythagorean Theorem:
a² + b² = c²
You can identify that x is the hypotenuse, as it is opposite to the right angle.
So:
3² + √11² = x²
9 + [(√11) (√11)] = x²
9 + 11 = x²
20 = x²
√20 = √x²
√4√5 = x
2√5 = x
x = 2√5

4) m∡BCA = 14 m∡ABC = 83
Step-by-step explanation:
Since DE is a line it has 180 degrees so:
103 + CAB = 180
CAB = 77 degrees
All triangle interior angles of a triangle add up to 180 degrees, so:
BAC + ACB + CBA = 180
3x - 14 + 3x + 9 + 77 = 180
6x + 72 = 180
6x = 108
x = 18
Plug in your values:
3(18) - 14 = 40
3(18) + 9 = 63

Find cos(B) in the triangle.
Answers
Step-by-step explanation:
[tex] \cos( \beta ) = \frac{5}{13} = 0.385[/tex]
Cos (B) in the right angled triangle is 5/13 .
Given,
Right angled triangle .
Now,
In right angled triangle
Perpendicular = 12
Base = 5
Hypotenuse = 13
So,
According to trigonometric functions,
CosФ = base / hypotenuse
sinФ = perpendicular / hypotenuse
tanФ = perpendicular / base
So,
Substitute the value in the function of cos,
Cos(B) = base / hypotenuse
Cos(B) = 5 / 13
Thus the value of function cos (B) is 5/13 .

The area of the sector which is the white triangle adding the shaded region is 68.9/360*π*9.28^2=51.78005(rounding to 5th digit after decimal point for accuracy before we do final round for answer)
The area of the white triangle in the sector has area 1/2*9.28^2*sin(68.9)= 40.17223(rounding to 5 digits again for some accuracy.
Now we take out the white triangle from the sector.
51.78005-40.17223=11.60782
rounding to the nearest tenth we get 11.6 cm^2
