Answer:
4x4x8x2 = 256
Step-by-step explanation:
The value of the angle R in the right triangle PQR is sin⁻¹ 6 / 8
The situation forms a right angle triangle.
<h3>How to find an angle in a right triangle?</h3>
The angle R can be found as follows:
using trigonometric ratios,
sin R = opposite / hypotenuse
Therefore,
opposite sides = 6
hypotenuse = 8
sin R = 6 / 8
R = sin⁻¹ 6 / 8

Answer:
Let y represents the dog and x represents the Cat.
As per the Statement:
A total of 34 dogs and cats participated in the pet store’s adoption event.
⇒ x+y = 34 ......[1]
It is also given that the number of dogs that were adopted was 7 more than twice the number of cats.
"Twice times the number of cats" means 2x
"7 more than twice the number of cats means 2x + 7
⇒
Then, system of equations are;
x +y = 34
y = 2x + 7
Now, plot the graph of these equation as show below:
The point intersection is, (9, 25) which represents 9 cats and 25 dogs are participated in the pet store's adoption event.
