Can someone help me

Mathematics
1 answer:
worty [1.4K]3 years ago
7 0

Answer:

B = 129

Step-by-step explanation:

Opposite angles of a parallelogram are equal (or congruent)

A and C are both 51.

All angles in a parallelogram equal 360

Take both the known angles and substract from 360, than divide by 2.

B = (360 - 51 - 51)/2

B = 129

V + 9<br> ---------- = 8 <br> 3<br><br> Can someone help me ??
bagirrra123 [75]
\frac{v + 9}{3} = 8

Multiply both sides by 3, because 3 is our denominator (bottom number in a fraction), and we want to get rid of the denominator.

3 × (v + 9) = 8 × 3

Simplify.

3v + 27 = 24

Then, subtract both sides by 27.

3v = 24 - 27

Simplify.

3v = -3

Divide both sides by 3.

v = -1

Which expression gives the magnitude of the magnetic field in the region c &lt; r2 &lt; b (at e?
BaLLatris [955]

The electric currents and magnetic materials have an effect called magnetic field. This magnetic field is specified with its direction and magnitude. The magnitude is the strength of the field.

the magnetic field at a distance r from a long straight wire carrying current I can be calculated with the equation:

B = μ​​ ​I / 2 pi R​​

where <span>μ​​ is a constant, I is the current and R is the radius. </span>

The table shows the steps for solving the given inequality for x.
slavikrds [6]

Given inequality -3(4-6x) < x+5.

We have -3 in front of Parenthesis.

That represents multiplication of -3 and Parenthesis.

The multiplication of Parenthesis could be done by applying distributive property.

On distributing, we get

-12+18x < x+5

x is added on right side of the inequality. The reverse operation of addition is subtraction. So we need to subtract x from both sides, we get

-12+18x-x < x-x+5

-12+17x < 5

Now, we need to get rid -12 from left side.

So, we need to apply addition property of equality, we need to add 12 on both sides, we get

-12+12+18x < x+5+12

17x < 17

We need to get rid 17 from left side. So we need to apply division property of equality.

On dividing both sides by 17, we get

17x/17 < 17/17

x<1.
