What is the correct height ?
1 answer:
Answer:
30 Inches
Step-by-step explanation:
Please refer to the image we have attached to this.
The frame is ABCD and The diagonal is AC, which is 50 inches long and making an angle of 36.87° from the bottom of the frame.
We are asked the height of the frame which is h in this image. We are going to use the trigonometric ratios in order to find the same.
° =
hence height of the frame is 30 inches

Step-by-step explanation:
Properties of a circumcenter;
1). Circumcenter of a triangle is a point which is equidistant from all vertices.
2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.
From the picture attached,
9). AG = GB = GC = 21
10). BC = 2(DC)
= 2×16
= 32
11). By applying Pythagoras Theorem in ΔGFB,
GB² = GF² + FB²
(21)² = GF² + (19)²
441 = GF² + 361
GF² = 441 - 361
GF =
GF = 8.9
12). By applying Pythagoras theorem in ΔGDB,
GB² = DG² + BD²
(21)² = (DG)² + (16)² [BD = DC = 16]
DG² = 441 - 256
DG = √185
DG = 13.6
