Answer:

x = 70 y = 140

Step-by-step explanation:

Apologies if I get any names of vocabulary terms wrong, I never pay much attention to the names.

The central angle measure of an arc is the same as the arc's measure. In this case, y is the central angle and 140 is the arc's measure, so y = 140.

The inscribed angle measure of an arc is 1/2 the arc's measure. An inscribed angle lies on the circle. So 140/2 = 70 = x.

Answer: 1.) 14.66666666666667
2.) 20

Steps:
1.) 180 = 3x + 136
180 -136 = 3x
44 = 3x
44/3 = x
14.66666666666667 = x

2.) 70 + x = 90
x = 90 - 70
x = 20

I would appreciate brainliest if this was helpful and correct! ;)

A flagpole casts a shadow that is 12 ft long. A 6-ft tall man casts a shadow

Vikentia [17]

Answer:

9ft

Step-by-step explanation:

Since the triangles are similar, the corresponding sides are proportional.

Let the height of the flag pole be x feet.

$\frac{x}{6} = \frac{12}{8}$

We multiply both sides by 6 to get:

$x = \frac{12}{8} \times 6$

We reduce the fraction to get:

$x = \frac{3}{2} \times 6$

We now simplify

$x = 3 \times 3$

$x = 9ft$
