Opposite angle of a quadrilateral add up to 180 degrees.

This means Angle A plus Angle C equal 180.

We can solve for X using that, then solve for Angle B.

2x-7 + x +4 = 180

Simplify:

3x -3 = 180

Add 3 to each side:

3x = 183

Divide both sides by 3:

x = 183 /3

x = 61

Now we know x, replace x with 61 in the equation for Angle B:

Angle B = 2x+3 = 2(61) +3 = 122 +3 = 125 degrees.

The value of x is 103.

The value of x is 59.

The value of x is 134.

The value of x is 12

The value of x is 50

The value of x is 135

<h3>What is the value of x?</h3>

The sum of angles on a straight line add up to 180 degrees.

180 - 77 = 103

180 - 121 = 59

180 - 46 = 134

12 x + 36 = 180

12x = 180 - 36

12x = 144

x = 12

24 + 3x + 6 = 180

3x = 180 - 24 - 6

3x = 150

x - 50

\frac{x}{3} + 99 + 36 = 180

\frac{x}{3} = 180 - 36 - 99

\frac{x}{3} = 45

x = 45 x 3

x = 135

Using Pythagorean, a^2 + b^2 = c^2
16 +x^2 = 36.69
Then subtract the 16 from 36.69, which is 23.69
And finally take the square root of that, giving you 4.87

Every summer I drive to Michigan. It is 3900km to get there. If I average 100km/hr, how much time will I spend driving?
motikmotik

Answer:

39 hours.

Step-by-step explanation:

You divide 3900 km by 100 km, (3900/100) and get 39. Since you are driving 100 km per hour, it will take you 39 hours to get to Michigan.
