What Is two thirds of a straight angle

1 answer:

5 0

A straight angle = 180 degrees

so 2/3 of a straight angle is 2/3 of 180..." of " means multiply
2/3(180) = 360/3 = 120 <==

The equation for line t can be written as y = 4x - 8. Line u, which is perpendicular to line t,

xeze [42]

Here, we are required to determine the equation of the line u which is perpendicular to the line t and passes through the point (8,8).

The equation of the line u is;. y = (-x/4) + 10.

First, the product of the slope of 2 perpendicular lines is negative 1 i.e -1.

M1 × M2 = -1

From observation, the slope of line t given by y = 4x - 8 is equal to 4.

Therefore, since M1 = 4,
Then, M2 = -1/4

To get the equation of a line,

Slope, M2 = (y - y1)/(x - x1)

where M2 = -1/4 , y1 = 8 and x1 = 8.

Therefore, -1/4 = (y - 8)/(x - 8).

Therefore, -x + 8 = 4y -32

Therefore, 4y = -x + 40.

Ultimately, the equation of the line u is ;

y = (-x/4) + 10.

4x+3y=-6 standard to slope intercept form

miss Akunina [59]

Answer:

y = -4/3x -2

Step-by-step explanation:

Slope intercept for is y = mx+b where m is the slope and b is the y intercept

4x+3y=-6

We need to solve for y

Subtract 4x from each side

4x-4x+3y=-4x-6

3y = -4x-6

Divide each side by 3

3y/3 = -4x/3 -6/3

y = -4/3x -2

The slope is 4/3 and the y intercept is -2

What is the value of t on the truss of the bridge?

IceJOKER [234]

Answer:

Step-by-step explanation:

t° + 55° = 90° (Exterior angle of a triangle is equal to the sum of the opposite interior angles.)

${t}^{o} + {55}^{o} = {90}^{o} \\ {t}^{o} = {90}^{o} - {55}^{o} \\ {t}^{o} = {35}^{o} \\$
