Answer:
531 in^2
Step-by-step explanation:
21 x 18 = 378 in^2
17 x 9 = 153 in^2
378 + 153 = 531 in^2
Answer:
The answer is 360 ways
Step-by-step explanation:
There is a little-known theorem to solve this problem.
The theorem says that
In a triangle, the angle bisector cuts the opposite side into two segments in the ratio of the respective sides lengths.
See the attached triangles for cases 1 and 2. Let x be the length of the third side.
Case 1:
Segment 5cm is adjacent to the 7.6cm side, then
x/7.6=3/5 => x=7.6*3/5=
4.56 cm
Case 2:
Segment 3cm is adjacent to the 7.6 cm side, then
x/7.6=5/3 => x=7.6*5/3=
12.67 cmThe theorem can be proved by considering the sine rule on the adjacent triangles ADC and BDC with the common side CD and equal angles ACD and DCB.
Answer:
D, -77 5/8
Step-by-step explanation:
6 3/4 = 27/4 = 6.75
6.75 x -11.5 = -77.625 or -77 5/8
2x + 5 > 3x + 1
<u> - 2x - 2x </u>
5 > x + 1
<u>- 1 - 1</u>
4 > x
x < 4
