Answer:
x = 11√3
y = 22
Step-by-step explanation:
In a 30-60-90 triangle, the hypotenuse is twice the shortest side.
y = 22
The long side is √3 times the short side.
x = 11√3
If you wish to use trigonometric functions:
sin 30° = 11 / y
1/2 = 11 / y
y = 22
tan 30° = 11 / x
1 / √3 = 11 / x
x = 11√3
Multiply all 4 by each other.
Answer:
13
Step-by-step explanation:
12^2 + 5^2 = c^2
144 + 25 = c^2
169 = c^2
13 = c

Answer:
175 ft
Step-by-step explanation:
From the question,
(a) ΔABC and ΔEDC are similar because all the angles in ΔABC is equal to the corresponding angles in ΔEDC.
I.e, ΔABC is equiangular to ΔEDC. (AAA).
(b) From the diagram.
for similar angle, ratio of corresponding sides are equal
100/d = 4x/7x
100/d = 4/7
where d = distance across the river
solve for d
d = (100×7)/4
d = 175 ft
