Answer:
X = 18
Y = 9√3
Step-by-step explanation:
use sin equation for right angle triangle
The sine of the angle
= ( the length of the opposite side ÷ the length of the hypotenuse.)
according to this question,
sin 30 = 9 / X
1/2 = 9 / X
X = 18
use cosine to find y
The cosine of the angle
= (the length of the adjacent side ÷ the length of the hypotenuse.)
cos 30 = y/x
√3/2 = y/ 18
y = 9 ✓3
Answer:
i
Step-by-step explanation:
This is the answer you get when you square and you get a negative number.
Answer:
160 m
Step-by-step explanation:
For the 15-deg angle, h is the opposite leg.
The hypotenuse is 628 m.
The trigonometry ratio that relates the opposite leg and the hypotenuse is the sine.
sin A = opp/hyp
Rounded to 2 significant figures:
h = 160 m
