Answer:

a° = 58°

b° = 48°

c = 74°

d° = 122°

Step-by-step explanation:

Angles on a straight line add up to 180°

58° + d° = 180°

d° = 180° - 58° = 122°

Alternate angles are equal.

a° = 58°

Angles in a triangle add up to 180°.

48° + 58° + c° = 180°

106° + c° = 180°

c° = 180° - 106° = 74°

Angles on a straight line add up to 180°

74° + 58° + b° = 180°

132° + b° = 180°

b° = 180° - 132° = 48°

How long is the arc intersected by a central angle of 5pie/3 radians in a circle with a radius of 2ft rounded to the nearest ten

lubasha [3.4K]

Radius of a circle: r = 2 ft
Central angle: α = 5 π /3 = 300°
Arc Length = 2 · 2 · π · 300/360 = 2 · 2 · 3.14 · 5/6 = 10.4666 ft ≈ 10.5 ft
Answer:
C ) 10.5 ft

Simplify your answer as much as possible

Answer:

-4u^2/y+(5/2)y^3u^2

Step-by-step explanation:

The applicable rules of exponents are ...

(a^b)(a^c) = a^(b+c)

(a^b)/(a^c) = a^(b-c)

$(8y^2u^7-5y^6u^7)\div(-2y^3u^5)=\dfrac{8y^2u^7-5y^6u^7}{-2y^3u^5}\\\\=-4y^{2-3}u^{7-5}+\dfrac{5}{2}y^{6-3}u^{7-5}=\boxed{\dfrac{-4u^2}{y}+\dfrac{5}{2}y^3u^2}$
