Answer:

Step-by-step explanation:

4x + 15 = 3

Subtract 15 from both sides

4x + 15 - 15 = 3 - 15

4x = -12

Divide both sides by 4

4x/4 = -12/4

x = -3

Check:

substitute x = -3 in the LHS of the equation,

4*(-3) + 15 = -12 + 15

= 3 = RHS

Trig: A sector of a circle has area 25 cm2 and centralangle

Alchen [17]

Answer: Radius = 10 cm and Arc length = 5 cm

Step-by-step explanation:

The area of a sector with radius r and central angle $\theta$ (In radian) is given by :-

$A=\dfrac{1}{2}r^2\theta$

Given : A sector of a circle has area $25 cm^2$ and central angle 0.5 radians.

Let r be the radius , then we have

$25=\dfrac{1}{2}r^2(0.5)\\\\\Rightarrow\ r^2=\dfrac{2\times25}{0.5}\\\\\Rightarrow\ r^2=\dfrac{50}{0.5}=100\\\\\Rightarrow\ r=\sqrt{100}=10\ cm$

Thus, radius = 10 cm

The length of arc is given by :-

$l=r\theta=10\times0.5=5\ cm$

Hence, the length of the arc = 5 cm
