Find m < ABC.

Answers

Answer:

m<ABC=51°

Step-by-step explanation:

The inscribed angle is half the measure of the intercepted arc. This means that angle ABC=1/2 arc AC

Using this, let's make an equation

5x+11=(1/2)(16x-26)

5x+11=8x-13

11=3x-13

24=3x

x=8

Now go back to angle ABC and substitute for x

5(8)+11=51

m<ABC=51°

Answer:

m<ABC = 51

Step-by-step explanation:

m<ABC = 1/2 arc AC

(5x + 11) = 1/2(16x-26)

x=8

Plug it in

5(8) + 11 = 51

Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon

Answers

Answer:

9 sides

Step-by-step explanation:

Each interior angle of a regular polygon is 100 degrees larger than the exterior angle determine the number of sides of the polygon

Interior angle + exterior angle =

180°

Let x be the exterior angle.

Exterior angle = 180-x = 100 + x

= 180 - 100 = x + x

80 = 2x

x = 80/2

x = 40

Number of sides of the polygon =

= 360°/Exterior angle

Exterior angle = 40°

= 360/40 = 9 sides

Answers

Answer:

3/8 , 3/6. 3/4

Tad drove the least miles because the miles ridden is less than both 3/6 and 3/4 miles

Dale rode the second greatest mile because the miles ridden is greater than 3/8 but less than 3/4

Harrison rode the greatest mile because the miles ridden is greater than both 3/6 and 3/8

Step-by-step explanation:

to order the miles ridden , convert the fraction to decimals. to do this, divide the numerator by the denominator

3/4 = 0.75

3/6 = 0.5 miles

3/8 = 0.374

Find the missing angle

Answers

Answer:

If this is a parallelogram:

∠y = 112°

corners opposite the 112° corners = 68°      [(360° - 112° - 112°)/2 = 68°]

∠z = 68° - 40° = 28°

∠x = ∠z = 28°

Answer:

x = 28°, y = 112°, z = 28°

Step-by-step explanation:

suppose it's a parallelogram,

in a parallelogram, opposite angles are congruent: y = 112°

40 + 112 + x = 180

=> x = 28°

If 2 lines are cut by a transversal, then the alternate interior angles are congruent: x = z => 28° = z

If –8x + 2y = -4 is a true equation, what would be the value of 40x – 10y?

Answers

If u need to find the values for X & Y I believe this is the right answer

X = 1 —— Y = 2
-8x + 2y = -4
-8(1)+ 2(2) = -4

40x - 10y
40(1) - 10(2)
40 - 20 = 20
