Answer:
D) 330 cm²
Step-by-step explanation:
The area of a rectangle is the product of its length and width. Your rectangle has an area of ...
(15 cm)(22 cm) = 330 cm²
To figure this out, use the acronym SOHCAHTOA to determine which trigonometric function to use.
8 is opposite to <R and 3 is adjacent to <R so we use tangent.
Set up the following equation: tan(x)=8/3
Find the inverse (aka. tan^-1): x=69.44
So your answer is <R=69.4 degrees

Answer:
(3√3 + 3√10)/3√5
Step-by-step explanation:
Radical means square root.
√3/5 + √2/45 = (3√3 + 3√10)/3√5
Note : √45 = √9 × 5 = √ 9 × √ 5 = 3√5
11+i
that’s the answer hope it helps:)
