The statement EF=2.GF (Option A) and the statement
(Option C) are true for the ΔEFG.
<h3>What are trigonometric ratios?</h3>
The six trigonometric ratios of a right-angle triangle are Sin, Cos, Tan, Cosec, Sec and Cot. Trigonometric ratios are used to measure the sides of the right triangle.
Given that in ΔEFG, m∠E=30°, m∠F=60° and m∠G=90°.
Wow, sin 30°
⇒
⇒EF=2.GF
and sin 60°

⇒
Therefore, the statement EF=2.GF (Option A) and the statement (Option C) are true for the ΔEFG.

A = 360 cm^2
Step-by-step explanation:
Using Pythagorean theorem, the length AB is given by
AB^2 = 17^2 - 8^2 = 225 cm^2
or
AB = 15 cm
Since the ratio BC: CD = 1:2 and BC = 8 cm, this means that CD = 2×(8 cm) = 16 cm
so the length BD is
BD = BC + CD = 8cm + 16 cm = 24 cm
There the area of the rectangle is
A = AB×BD
= 15cm×24cm
= 360 cm^2
Answer:
693
Step-by-step explanation:
7 x 9 x 11 =693
Answer:
Step-by-step explanation:
For this case we can use the figure attached and we are interested in order to find the value of x.
We have two similar triangles (DEC and ABC) and we can find the scale factor like this:
And now we can apply proportions in order to find the value of x using the two sides DE and BA, since we have the ratio between the triangle DEC and ABC we have this:
And solving for x we got:
And then the distance across the lake would be 2000 ft
