(1) If DF = FB, then point F is called the _____ and segments DF and FB are _____.
Vesnalui [34]

Answer:

(1) C

(2) C

(3) 4

(4) False

Step-by-step explanation:

(1) If DF = FB, then point F is called the midpoint and segments DF and FB are congruent.

(2) If ray FA bisects angle EFB, then angles EFA and AFB are congruent.  If measure of angle EFA = 47 degrees, the measure of angle EFB = 47 degrees.

(3) If  DF = x+2,  FB = 2x+1 and DB = 15, then

DF + FB = DB

x+2+2x+1=15

3x+3=15

3x=15-3

3x=12

x=4

(4) If x=4, then

DF=4+2=6

FB=2·4+1=9

Since DF is not congruent to FB, F is not a midpoint. False

Find measure.<br> m ∠ 5
jeka57 [31]

Measure of angle 5 i.e. m∠5 = 50°

<h3>What is measurement of an angle ?</h3>

The measurement of angle is the degree of that angle or we can also say that the angles are always measured in degree. In geometry, the complete one revolution of four quadrants is of 360 degrees (360°) and divided into total of 360 parts where each part of this represents a degree.

<h3>How to  find angle measurement ?</h3>

As stated above there are total 360 parts in one revolution thus thus we can find value of particular angle by subtracting the angle from 360 or 180 for a straight line.

In the question,

Let given angle is ∠8.

Given, ∠8 = 50°

Now, according to vertical angle property

∠5 = ∠8

therefore, ∠5 = 50°

Thus, m∠5 = 50°

Elena L [17]

Answer:

10 feet

Step-by-step explanation:

18 × 2 = 36

56 - 36 = 20

20 ÷ 2 = 10

To check work, add all lengths together. 4 sides. 18 + 18 + 10 + 10 = 56

11x + 2y = 68 &amp; 5x + y = 13
matrenka [14]

Answer:

i hope its correct

Step-by-step explanation:

11x + 2y=68 ------------1

5x+y=13 ------------2

y= 13-5x. ------------3

put 3 into 1

11x +2(13-5x) =68

11x +26 -10x =68

x=42

put x =42 into 2

5(42) +y =13

210+y=13

y=13-210

y=197
