What is the question asking? i dont know if you want to find the angle (which is 90 degrees) or if you ant to find 24^2 (which is 576) or if you want the square route (which is 4.89897948557 or simplified to the nearest tenth its 4.9)
Answer:
Solution,
Here,∠FGD=∠CGE=30°[Being vertically opposite angles]
Now we have,
90°+∠CGE+x=180°
or,90°+30°+x=180°
0r,x=180°-30°-90°
→x=60°
Step-by-step explanation:
Represent the thickness of the frame by x. Framing the mirror will increase both its length and width by 2x. The area of the mirror with the frame is the product of the length and width which can mathematically be expressed as,
A = (3 + 2x)(2 +2x) = 8
The equation above can be simplified into 4x^2 + 10x -2 = 0. This equation can still be further simplified by dividing it by 2. However, it will give an answer which is not found on the choices. Thus, the answer is the third choice.
