X = 16 18 34 can someone explain please?
Leno4ka [110]

Answer:

x = 16

Step-by-step explanation:

(whole secant) x (external part) = (tangent)^2

(x+2) * 2 = 6^2

2(x+2) = 36

Divide each side by 2

x+2 = 18

Subtract 2

x+2-2 = 18-2

x = 16

A toolbox contains a pile of mixed up pile of wrenches. The wrenches are all labeled with the dimension of their openings in fra
Sergio039 [100]
1.

     a)Two different methods for ordering these wrenches are either
     converting the measurements into decimal or converting them into
     fractions. 

     b) I chose to convert them into fractions with an LCD of 16. The fractions
     are: 8/16, 12/16, 6/16, 10/16, 5/16, 7/16, 11/16

     c) The ordered form of the fractions, from least to greatest, is 5/16, 3/8,
     7/16, 1/2, 5/8, 11/16, 3/4

2. I don't see how I can put them on a number line. 

3. The number line can definitely be used to support the answer from part C (if it is done correctly). That is because if the order on the number line is the same as the order in C, then we know that C is correct. In addition, since the number line includes benchmarks, we can easily see if the answer to C is incorrect.

If the measure of angle BCD=51 degrees, solve for x.
BabaBlast [244]

Answer:

x=5

Step-by-step explanation:

step 1

Find the measure of angle EFD

In this problem I will assume that ABCD is a parallelogram

In a parallelogram opposite angles are congruent and consecutive angles are supplementary

so

m\ angle BCD=m\angle BED=51^o

m\ angle FED=(1/2)m\angle BED=(1/2)51^o=25.5^o --- > given problem

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle EFD

m\ angle FED+m\ angle FDE+m\ angle EFD=180^o

substitute the given values

25.5^o+55^o+m\ angle EFD=180^o

80.5^o+m\ angle EFD=180^o

m\ angle EFD=180^o-80.5^o

m\ angle EFD=99.5^o

step 2

Find the measure of angle EFB

we know that

m\angle EFB+m\angle EFD=180^o ---> by supplementary angles

we have

m\ angle EFD=99.5^o

substitute

m\angle EFB+99.5^o=180^o

m\angle EFB=180^o-99.5^o

m\angle EFB=80.5^o

step 3

Find the value of x

Remember that the sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle EBF

m\ angle BEF+m\ angle EFB+m\ angle EBF=180^o

we have

m\angle BEF=m\ angle FED=25.5^o

m\angle EFB=80.5^o

m\angle EBF=(14x+4)^o

substitute

25.5^o+80.5^o+(14x+4)^o=180^o

solve for x

Combine like terms

(14x+110)^o=180^o

14x=180-110

14x=70

x=5
