The measure of base angle of the isosceles right angle triangle is 45°.

A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any angle is a right angle.

Given that,

Triangle ABC is an isosceles right angle triangle.

In an isosceles triangle, two sides are equal and corresponding angles are equal.

Let the corresponding angles are α and α.

Since, one angle of right angle isosceles triangle is 90°.

Also, the sum of angles of triangle is 180°

Implies that,

α  + α  + 90 = 180

2α  = 180 - 90

2α  = 90

α  = 45

The required value of angle α  is 45°

Step-by-step explanation:

This equation is in y=mx+b form, so to graph this equation, take the y-intercept which would be 12. Go on your graph and make twelve on the y-axis (you can go by two's or even six's). Then take your slope which would be -6 and use rise of run which would be down 6, since it's negative, and to the right one. Keep repeating this process until you ran out of space. Draw a line between the points and you have graphed a line.

Answer:

Step-by-step explanation:

a) Friction opposes motion, so is in the opposite direction of the net force on the sled. Taking "left" to be "positive", the two animals are applying a net force of +42 N -15 N = 27 N. That is to the left, so the friction force is to the right.

__

b) The total of forces applied by the animals and friction is ...

  27 N -5 N = 22 N . . . to the left

__

c) Acceleration can be found from the relation ...

  a = F/m . . . . 'm' is mass

  a = (22 N)/(15 kg) = 22/15 m/s² . . . . 'm' is meters

__

d) The coefficient of friction is the ratio of friction force to the normal force on the surface producing the friction. Here, that normal force is the force due to gravity acting on the 15 kg mass of the sled.

 coefficient of friction = (5 N)/(9.8 m/s²·15 kg) = 5/147

 coefficient of friction ≈ 0.034

Answer:

1. to the right

2. 22 N

3. 22/15 ≈ 1.467 m/s²

4. 5/147 ≈ 0.034

Step-by-step explanation:

8x - 13 = 5x + 17 (DE = EF)

8x - 5x = 17 + 13

3x = 30

x = 10

Ratios can be divided into part-to-part ratios and part-to-whole ratios. Part-to-part ratios provide the relationship between two distinct groups

Answer:

x = 1

Step-by-step explanation:

x / 5 = 5 / 25,

Divide the denominators bigger one to smaller one, then that is the numerator for the larger fraction.

do 5 divided by 5 which is 1

Or a more simple way,

1/5 = 5/25   multiply 1/5 by 5 top and bottom which gets 5 / 25

Answer:

x = 1

Step-by-step explanation:

Step 1: Cross-multiply

x*(25) = (5)*(5)

Step 2: Divide both sides by 25.

Answer:

r = 24

Step-by-step explanation:

Just reverse everything,

3 x 16 = 48,

48 ÷ 2 = 24,

to double-check,

if you plug in 24 for r then you have,

2(24)/3 = 16

48/3 = 16

16 = 16

The discriminant is greater than zero, the equation has 2 solutions

Given the quadratic expression as shown:

-x^4 + 4x + 1 + 3 = 0

x^4 - 4x - 4 = 0

The discriminant is given as b^2 - 4ac

where;

a = 1

b = -4

c = -4

Substitute

D =(-4)^2 - 4(1)(-4)

D = 16 + 16
D = 32

Since the discriminant is greater than zero, the equation has 2 solutions

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

Given data ,

The number of marbles Peter had on his way home = 171

The amount of marbles he lost on his way home = ( 3/4 ) th

Now , the amount of marbles Peter have left = 1 - amount of marbles he lost on his way home

The amount of marbles Peter have left = 1 - 3/4

                                                                = ( 1 / 4) th

So , The number of marbles Peter had left when he arrived home is =

Amount of marbles Peter have left x Number of marbles Peter had

The number of marbles Peter had left when he arrived home is = (1/4) x 171

= 171 / 4

= 42.75

≈ 43 marbles

Hence , the number of marbles Peter had left when he reached home is 43

Answer:

The answer is: y = 9.25x

Step-by-step explanation:

Let the equation for the proportionality relation is y = mx .......... (1), where y represents the money that Craig earns for a duty of x hours.

Here, m is the constant of proportionality and we have to find its value.

Given that Craig earns $37 for 4 hours duty.

So, from equation (1), we have 37 = 4m, ⇒ m = 9.25

Therefore, the equation becomes y = 9.25x. (Answer)
