Answer:
<h3>x = 49.6°</h3>
Step-by-step explanation:
Find the image attached;
From the image;
opposite side = 16
Hypotenuse = 21
Angle of inclination = x
Using the SOH identity
sinx = opposite/hypotenuse
sin x = 16/21
sin x = 0.7619
x = arcsin 0.7619
x = 49.6° (to the nearest tenth of a degree)
D.) x = 40
E.) x = 12
F.) x = 32
G.) x = 12.25
H.) x = 9
I.) x = -3
Answer:
32.5
Step-by-step explanation:
If CED is 65, then AEB is 65, therefore we can calculate that CEA is 115 because 180 - 65 = 115. Then we do 180 - 115 = 65 which is the sum of angles ACE and CAE so 65 / 2 = 32.5 which is CAE.
Hope this helped!
Answer:
see explanation
Step-by-step explanation:
Using the identity
tan²x = sec²x - 1
Consider left side
sec²x + tan²x
= sec²x + sec²x - 1
= 2sec²x - 1
= right side , thus verified
