TrianglesABC and DEF are <br> Similar<br> Not similar
puteri [66]

Answer:

Similar

Step-by-step explanation:

We can say that the triangles are similar by looking at the angle measurements

Angle B = 35

Angle F = 55

Both angles A and D = 90 because these are right triangles

We can say the measure of angle E = 35 because the sum of angles in a triangle equal to 180

Same rule applies to angle C

Find the value of x. write your answer in simplest radical form
BartSMP [9]

Answer:

<h2>x = 4 \sqrt{2}</h2>

Step-by-step explanation:

To find the value of x we can use either sine or cosine

Using cosine we have

<h3>\cos(\theta)  =  \frac{adjacent}{hypotenuse}</h3>

From the question

x is the hypotenuse

4 is the adjacent

We have

<h3>\cos45=  \frac{4}{x}  \\ x \cos45 = 4 \\ x =  \frac{4}{ \cos(45) }</h3>

We have the final answer as

<h3>x = 4 \sqrt{2}</h3>

Hope this helps you
