Answer:
14.90cm [a]
Step-by-step explanation:
To find x, we will apply " sine rule"
that is, A/a=
B/b
here a= x A=90° B=70°anb b =14cm
so we input the values we have
1/x =0.94/14
cross multiply,
0.94x = 14
x = 14/0.94
=14.90cm
Answer:
Therefore the Distance across the Pond is
Step-by-step explanation:
Given:
Triangle are Similar
AB = 90 ft
AC = 170 ft
BD = 207 ft
DE = x
To Find:
x = ?
Solution:
In Δ ABC and Δ DBE
∠A ≅ ∠D …………..{ measure of each angle is 90° given }
∠ABC ≅ ∠DBE ……….....{Vertical Angle Theorem}
Δ ABC ~ Δ DBE ….{Angle-Angle Similarity test}
If two triangles are similar then their sides are in proportion.
Substituting the values we get
Therefore the Distance across the Pond is
