So probability is (desired outcomes)/(total possitlble outcomes)
desired is 1 since 3 appaears once on the cube
6 total possible
so probaity of rolling a3 is 1/6
100 times
100 times 1/6=100/6=16 and 2/3 times
round up
17 times
a) The length of p is 21.4 cm
b) The measure of angle P is 45.6°
<h3>Trigonometry </h3>
From the question, we are to determine the length of p
From the <em>Pythagorean theorem</em>, we can write that
30² = 21² + p²
p² = 30² - 21²
p² = 900 - 441
p² = 459
p = √459
p = 21.4 cm
∴ The length of p is 21.4 cm
b)
Measure of angle P
Using SOH CAH TOA

cos P = 0.7
P = cos⁻¹(0.7)
P = 45.6°
Hence, the measure of angle P is 45.6°

Answer:
10x - 17
Step-by-step explanation:
Perimeter is the sum of all sides
5x - 7 + (3x - 4) + (2x - 6)
10x - 7 - 4 - 6
10x - 17
