Answer:

arc BC = 84 degrees

Step-by-step explanation:

notice:

need to find n  before finding arc BC

(13n -16) + (7n + 12) + 6n = 360

13n + 7n + 6n  - 16 + 12  = 360

26n  - 4 = 360

26n = 364

n = 364/26  = 14

so arc BC = 6*14 = 84 degrees

Geometry. I'm really struggling with this.
julia-pushkina [17]

Answer:

The measure of Angle G is 62.5°.

Step-by-step explanation:

Given:

Δ EFG is an Isosceles Triangle.

EG = EF

m∠ E = 55°

To Find:

m∠ G = ?

Solution:

Δ EFG is an Isosceles Triangle. ........Given

EG = EF                                   ..............Given

∠ G = ∠ F = x (say)              ..................Isosceles triangle property

Now in Δ EFG we have

∠ E + ∠ G + ∠ F = 180° .......... Angle sum property of triangle

On substituting the values we get

55 + x +x =180\\\\2x=180-55\\\\2x=125\\\\\therefore x=\frac{125}{2} =62.5\°\\\\\therefore x=62.5\°

The measure of Angle G is 62.5°.

The first section has 90 sheep sorted into 3 rows how many sheep are in each row of the first section
nexus9112 [7]

Answer:

30 sheep

Step-by-step explanation:

Given that the first section has 90 sheep sorted into 3 rows, assuming that each row has equal number of sheep, then the number of sheep per row will be the total number of sheep available divided by the number of rows

= 90/3

= 30

It means there are 30 sheep per row
