1 answer:

8 0

12.
sin(28) = 0.4694...
8/0.4694... = 17.0404...(That is the scale factor)
tan(28) = 0.5317...
17.0404... X 0.5317.... = 9.0605... ~ 9

13.
tan(37) = 0.75355...
5/ 0.75355... = 6.635...(SC)
sin(37) = 0.60181...
0.60181... X 6.635... = 3.9931... ~ 4

14.
∠E = 37
cos(37) = 0.7986...
8/0.7986... = 10.0170...(SC)
tan(37) = 0.75355..
10.0170... X 0.75355... = 7.5484... ~ 8

3/4 feet

You can set this up as an equation and solve

$5\frac{2}{3}-4\frac{11}{12} =5\frac{8}{12} -4\frac{11}{12} =4\frac{20}{12} -4\frac{11}{12}=\frac{9}{12} =\frac{3}{4}$

Answer:

3y = 60°, 2y = 40° , 4x = 104°, x = 26°, y = 50°

Step-by-step explanation:

Triangle g

180° = 80° + 3y + 2y

100° = 5y

y = 20°

Triangle h

y = 180° - 130°

y = 50°

180° = 4x + x + 50°

130° = 5x

x = 130 / 5

x = 26°
