Two pairs of corresponding angles

Irina18 [472]2 years ago

Answer:

Option C is correct.

Two pairs of corresponding angles

Step-by-step explanation:

Given triangle XYZ has been dilated to form triangle LMN.

Dilation states that it is a transformation that produces an image that is the same shape as the original, but of a different size.

therefore, the triangle XYZ  by a dilation is similar to triangle LMN

Similar figures have the

*same shape

*equal corresponding angle measures, and

*have proportional sides.

Therefore, the information which is needed to prove that two given triangles are similar is two pairs of corresponding angles

What is the measure of an angle whose sine is√3/2 ? 60 45 30
dem82 [27]
ANSWER

The required angle is
60 \degree

EXPLANATION

Let the angle whose sine is
\frac{ \sqrt{3} }{2}
be
x \degree

Then

\sin(x \degree)  =  \frac{ \sqrt{3} }{2}


We take the inverse sign of both sides to obtain,

x =  \sin ^{ - 1} ( \frac{ \sqrt{3} }{2} )

We use our scientific calculator to evaluate and obtain,

x = 60 \degree
