We know that an isosceles triangle has 2 equal sides.

We can represent the equal sides with x, and the base with y:

2x + y = 15.6

Given states that y = x - 3, so:

2x + x - 3 = 15.6

3x = 18.6

x  = 6.2

y = 3.2

The sides are 6.2 m, and the base is 3.2 m.

What is the positive root of the equation x2 + 5x = 150?<br> ao
fenix001 [56]

Answer:

10.

Step-by-step explanation:

x^2 + 5x = 150

x^2 + 5x - 150 = 0

This equation will factor:

(x - 10)(x + 15) = 0

x - 10 = 0 or x + 15 = 0, so:

x = 10 or -15.

What is the angular velocity of a 6–foot pendulum that takes 3 seconds to complete an arc of 14.13 feet? Use 3.14 for π.
RoseWind [281]
The angular velocity is defined by the position angle over time.
Get first the position angle of the pendulum which has the formula of s = rθ where s = arc length, r = radius (or length of the pendulum's string), and θ = position angle. Getting θ, we have <span>θ = s/r = 14.13 ft / 6 ft = 2.355 rad
Thus, the angular velocity is </span>θ/t where t = time; so 2.355 rad / 3 sec = 0.785 rad/sec
Hope this helps.
