This question is unsolvable,

because there is insufficient information (an angle)

If you have an angle you can use sine rule or cosine rule

sine rule: (sine(distance)) / angle = (sine(distance)) / angle

cosine rule: a² = b² + c² -2bc cos A

Type the correct answer in each box. Use numerals instead of words. If necessary, use / for the fraction bar.

Mars2501 [29]

Answer

-1 x + 2y = 4

Explanation

The first step is to get the gradient of the line.

The two points in the line are; (4,0) and (0,2).

slope = (2 - 0)/(0 - 4)

= 2/-4

= -1/2

To get the function we use one of the point (0,2) and a general point (x,y).

1/2 = (y - 2)/(x - 0)

1/2 = (y - 2)/x

(1/2)x = y -2

x = 2y - 4

x - 2y = -4

-1 x + 2y = 4

Points A, B, and C are midpoints of the sides of right triangle DEF.

Radda [10]

Answer:

1) True 2) True 3) False 4) True

Step-by-step explanation:

In this question let's verify those options

1.Triangle A B C is inside triangle D E F. (true)

If A, B and C are midpoints of DEF then connecting those midpoints we have an interior triangle.

2. Point A is the midpoint of side F D, point B is the midpoint of side D E, point C is the midpoint of side F E. (true)

3. Angles D F E and A B C are right angles. (false)

These triangles are similar. And In this case, the right angles are:

$E\hat{D}F\cong A\hat{C}B=90^{\circ}\\\measuredangle D=\measuredangle C=90^{\circ}$

D and C are opposed to the larger side, and not F, and B

Because: $\measuredangle F\cong\measuredangle B \neq90^{\circ}$

4. The length of D E is 10 centimeters, the length of F D is 6 centimeters, and the length of F E is 8 centimeters. (true)

Let's test this by the Pythagorean Theorem. For DE is the hypotenuse and FD and FE is their legs.

$\overline{DE}=\sqrt{FD^{2}+FE^{2}}\\\overline{DE}=\sqrt{8^{2}+6^{2}}\\10= \sqrt{100}\\10=10$
