Answer:
74°
Step-by-step explanation:
Let ½(theta) = X
Tan(X) = opposite/adjacent
= 7.5/10
X = (tan^-1)(0.75)
X = 36.8698976458
Theta = 2X = 2(36.8698976458)
Theta = 73.7397952916
Nearest degree: 74°
Similar triangles have corresponding sides with proportional lengths.
AB/BC = DE/EF
5/9 = 7.5/EF
5(EF) = 9 * 7.5
5(EF) = 67.5
EF = 13.5
Answer:
I think it's 9:50
Step-by-step explanation:
Tanx=opposite/adjacent
tan46=x/6 inches
1.035=x/6
x=6.21318
x=6.2
opposite=6.2
