Answer:

Question 1 -

The angles in a triangle always add up to 180 degrees.

Triangle 1 (the very left) -

Equation: 180 - (35 + 50) = x

x = 95

Triangle 2 (the middle) -

Equation: 180 - (60 + 90) = x

x = 30

Triangle 3 (the very right) -

Equation: 180 - (137 + 28) = x

x = 15

Step-by-step explanation:

All angles of a triangle add up to 180 degrees.

To write an equation to find the missing angle of a triangle given two angles, you have to first add together the two angles. In an equation, you have to write these added together in parenthesis to show that you need to add those together first. Then, at the beginning of the equation, you write "180 -" to show that you need to subtract the sum of the 2 angles from 180.

Hope it helps!

A spinning giant star of initial radius R1 and angular speed ω1 suddenly collapses radially inward reaching a new radius R2 = 0.

Answer:

K1/K2=4

Step-by-step explanation:

The kinetic energy of a rotating sphere is given by:

$K=\frac{I*\omega^{2} }{2}$

The moment of inertia of a solid sphere is given by

$I=\frac{2MR^{2} }{5}$

The initial kinetic energy is therefore

$K_1=\frac{2MR^{2}*\omega^{2} }{10}$

$K_1=\frac{MR_1^{2}*\omega^{2} }{5}$

The final kinetic energy is given by

$K_2=\frac{MR_2^{2}*\omega^{2} }{5}$

Therefore the relation K1/K2 if R2 = 0.5R1

$\frac{K_1}{K_2} =\frac{5M(R_1)^{2}*\omega^{2} }{5*M(0.5R_1)^{2} \omega^{2}}$

The text says nothing about the final angular velocity just the collapse of the collapse of the radius

$\frac{K_1}{K_2} =\frac{1 }{(0.5)^{2} }=4$

Describe the pattern that you see in the table for the right column. Please help me describe it in complete sentences. Extra poi

Gwar [14]

The pattern on the table is x increases:

The sine of x increases
The cosine of x increases
The function sin²(x) + cos²(x) remains constant

<h3>How to describe the pattern?</h3>

The functions on the table of values are:

sin(x), cos(x) and sin²(x) + cos²(x)

To describe the pattern, we simply observe how the values of the function change, as x increases.

As x increases, on the table:

The sine of x increases
The cosine of x increases
The function sin²(x) + cos²(x) remains constant

A board game has 25 cards, each printed with a number from 1 through 25. Sameer shuffled the cards, and then selected 1 card.

Yuki888 [10]

Total number of cards = 25 .
Total number of possible draws = 25
Number of possible successes = 5

(The successful draws are 1, 2, 3, 9, and 18.)

Probability of success = 5/25 = 1/5  = 0.2 = 20%
