Sine theorem:
a/sin A=b/sin B=c/sin C
Data:
A=33º
a=19
b=14
19/ sin 33º=14 / sin B
sin B=(sin 33º *14) / 19
sin B=0.41312...;
B=arcsin 0.41312...=23.66º
A+B+C=180º
33º+23.66º+C=180º
C=180º-33º-23.66º
C=123.34º
a/Sin A=c/sin C
19 / sin 33º=c / sin 123.34º
c=(19 * sin 123.34º) / sin 33º
c=29.14
Answer: a=19; b=14, c=29.14; A=33º; B=23.66º; C=123.34º
The rectangles are similar. The difference between 7 and 8 is that the second one is dilated by 1/2
5 goes into 2565...... 513 times because 2656 divided by 5 equals 513 2565 / 5 = 513
