Find the value of X.

Mathematics
1 answer:
andriy [413]3 years ago
6 0

Answer:

x=3

Step-by-step explanation:

All the angles added together must equal 360 degrees.

74+43+50+37+12x+12x+11x+17x = 360

Simplify the equation by adding like numbers.

204+52x=360

Subtract 204 from both sides of the equation.

204+52x-204=360-204

52x=156

Now, divide both sides by 52.

52x/52=156/52

x=3

Line a passes through that point (-8,-7) and has a slope of 5/8. Choose the equation that best represents A
GuDViN [60]

Answer:

y = 5/8 x -2

Step-by-step explanation:

Given that the slope of the line, m=5/8, which passes through the point (-8,-7).

Let the equation of the line be y=mx+c

where m is the slope of the line and c is a constant.

As m=5/8, so the equation of line become

y= 5/8x+c

As the line passes through the point (-8,-7), so putting y= -7 and x= -8, we have

-7 = 5/8(-8)+c

-7 = -5 + c

c= -7 + 5

c= -2

On putting the value of c, the equation of line become

y=5/8 x -2

Hence, the equation of the line is y = 5/8 x -2.

What is the slope of the diagonal line on the larger triangle? Explain how you found it.
Stolb23 [73]

Answer: 2/3 is the slope I think and for the same slope thing here is my answer:

We can use similarly of triangles in this case there will be a formation of 2 pairs equal ( angles formed by the y-axis on the parallel lines) angles between triangles formed as the y-axis lines are parallel. So,the slope is the same for both.
