Step-by-step explanation:

It appears that given geometrical shape is a HEXA-DECAGON or a 16 sided polygon.

Measure of one interior angle of hexa-decagon can be given as:

$\frac{(n - 2) \times 180 \degree}{n} \\ \\ = \frac{(16 - 2) \times 180 \degree}{16} \\ \\ = \frac{14 \times 45 \degree}{4} \\ \\ = \frac{7 \times 45 \degree}{2} \\ \\ = \frac{315 \degree}{2} \\ \\ = 157.5\degree \\$

In ∆PQR, ∠P = 90degrees , PQ= 12 cm, PR=16cm. Find ∠Q

siniylev [52]

Answer:

∠Q = 53.13 degrees

Step-by-step explanation:

Given that ∆PQR, ∠P = 90degrees , this means that the triangle is a right angled triangle

Hence using the notation

SOH CAH TOA

where S is sine, C is cosine, T is tangent and O, A and H represents the size of the opposite, adjacent and hypotenuse sides

Considering ∠Q and the given sides

PR=16cm is the opposite side,

PQ= 12 cm is the adjacent side hence we use TOA

Tan Q = 16/12 =

Q = Arc tan 16/12

= 53.13 degrees

Two cars start from the same point driving in opposite directions. Both cars drive 6miles. One car stops, the other car makes a

dimaraw [331]

Answer:

<u>14.4 mile</u>²

Explanation:

1. By driving 6 miles each, the cars will be 6 miles + 6 miles = 12 miles appart.

2. When one car stops and the other car makes a 90° left-hand turn and drive 8 miles, you can model the situation with a right triangle, where one leg is 12 miles, the other leg is 8 miles, and the hypotenuse is the distance that separates the cars.

Hence, you must use Pythagoras to find that distance.
