triangle equals 180 degrees

the two lower angles are  the same since it is an isosceles triangle

180= x+x+24

180 = 2x+24

subtract 24 from each side

156 = 2x

divide by 2

78 = x

Answer:

B. y=6x+9

Step-by-step explanation:

m=(y2-y1)/(x2-x1)

m=(-3-3)/(-2+1)= (-6)/(-1)= 6

m=6

y=mx+b       y=6x+b

plug in one of the points for b

-3=6(-2)+b    -3=-12+b  -3+12= 9

y=6x+9

A 45 kg skydiver has a speed of 25 m/s at an altitude of 950 meters above the ground. Determine the
Montano1993 [528]

The kinetic energy possessed by the skydiver is 14, 062. 5 Joules

<h3>What is kinetic energy?</h3>

Kinetic energy of an object is defined as the energy possessed by an object due to its motion.

It is also described as the work that is required to accelerate a body of mass from rest to its given velocity.

The formula for calculating kinetic energy is expressed as;

Kinetic energy = 1/2 mv²

Where;

  • m is the mass of the object
  • v is the velocity of the object

Now, substitute the values

Kinetic energy = 1/2 (45)(25)²

Find the square

Kinetic energy = 1/2 (45)(625)

Find the product

Kinetic energy = 1/2(28125)

Find the quotient

Kinetic energy = 14, 062. 5 Joules

Hence, the value is  14, 062. 5 Joules
