We are asked to determine the area of the given figure. To do that we will divide the figure into a square and a triangle. The area of the square is the product of its dimension, therefore, the area is:

The area of the triangle is given by the following formula:

Where "b" is the base and "h" is its height. Replacing the values:

The total area is the sum of both areas:

replacing the areas:
Simplife3^2 to 9
9x-7+2=0
9x-7+2to 9x-5
9x-5=0
add 5 to both sides 9x=5
Divide both sides by 9
x=5/9
The answer to this question is C. 11. (I am making a joke by mentioning the music disc C418 Music Disc Variation 11 from Minecraft. I hope you play or else you might not get the joke I implied.) Hoped this helped. (Also I am going for 10 Brainliest answers. I would greatly appreciate it if you chose mine as the Brainliest answer. Thank you 100 times in advance. :))
Answer: 21°
Step-by-step explanation:
Since angles DAE and CBE are inscribed on arc AC, they r equal
Hence angle CBE = 42°
So angle DAE = 42/2 = 21°
