Answer: 863

Step-by-step explanation:

There are two ratios in this problem, 220:500 and 380:x.

There are 220 tagged elk in a group of 500 elk counted.

There are 380 tagged elk in a group of x elk in the park.

The ratio of tagged elk to elk counted is the same as tagged elk to elk in the park. Solve for x.

Step 1: 500/220 = x/380

500/220 = 2.27

x/380 = 2.27

Step 2: Find the value of x.

x/380(380) = 2.27(380)

x = 862.6 = 863 (rounded)

Answer:

$\boxed{\stackrel{\Large\frown}{PQS}\:= 222°}$

Explanation:

Since $\overline{PR}$ is a diameter, arc $\stackrel{\Large\frown}{PQR}\:= 180°.$

Given that $\angle{SUR} = 42°$ is a subtended central angle by two diameters,

$\stackrel{\large\frown}{RS} \:= 42°$ .

Using the rule of arcs, $\stackrel{\Large\frown}{PQR} + \stackrel{\large\frown}{RS} \: = \: \stackrel{\Large\frown}{PQS}$ →

$180° + \: 42° = \: \stackrel{\Large\frown}{PQS}$

$222° = \: \stackrel{\Large\frown}{PQS}$

$\stackrel{\Large\frown}{PQS} \: = \: 222°$

Step-by-step explanation:

HK= FK/2= 16/2= 8

Using pythagoras theorem in triangle GHK,

GH²= GK²-HK²

= 17²-8²

= 225

GH= √225

=15
