Hello there!
Explanation:
↓↓↓↓↓↓↓↓↓↓↓↓↓
I gave you a hint.
You had to used PEMDAS.
P-Parenthesis
E-Exponents
M-Multiply
D-Divide
A-Add
S-Subtract
First you had to calculate with parenthesis first.
Then you calculate with exponents.
You had to multiply and divide you had go to left to right.
Then you add or subtract you had go to left to right.

Answer:
area = 44 cm²
Step-by-step explanation:
rectangle area = bh = 8 x 4 = 32 cm²
triangle height² = 5² - 4³ = 25 - 16 = 9
triangle height = 3
triangle area = 1/2bh = 1/2(8)(3) = 12 cm²
32 cm² + 12 cm² = 44 cm²
area = 44 cm²

Answer:
x = 10
Step-by-step explanation:
The mnemonic SOH CAH TOA reminds you of the relation ...
Sin = Opposite/Hypotenuse
sin(30°) = 5/x
Solving for x, we get ...
x = 5/sin(30) = 5/0.5
x = 10
_____
It can be helpful to remember that the side ratios in a 30°-60°-90° triangle are ...
1 : √3 : 2
That is, the hypotenuse is 2 times the length of the side opposite the 30° angle. Here, that means x = 2×5 = 10, as we found above.
