Answer:

x ≈ 8.8

Step-by-step explanation:

Using the sine ratio in the right triangle

sin20° = \frac{opposite}{hypotenuse} = \frac{PQ}{OQ} = \frac{3}{x} ( multiply both sides by x )

x × sin20° = 3 ( divide both sides by sin20° )

x = \frac{3}{sin20} ≈ 8.8 ( to the nearest tenth )

sergij07 [2.7K]

Hey there!

Guide to your question:

“More than” than means “addition” or “add”

“Product” means “multiplication” or “multiply”

So, your answer should be:

1.5 + g * h

Good luck on your assignment and enjoy your day!
