Help!!!? Does anyone know the answer to this question!!?
Likurg_2 [28]

Answer:

15.75

36

15.75

Step-by-step explanation:

Formula

the relationship between these two secants is NQ * NP = NM * LM

Givens

  • NP = 32
  • NQ = x
  • NM = 14
  • NL = 14 + 22 = 36

Solution

x*32 = 14*36                 Substitute values. Divide by 32

x = 14 * 36/32               Multiply 14 and 36    

x = 504/32                   Divide by 32

x = 15.75

The answer to the first box is 15.75 or x

The answer to the second box is

LM is assumed to be 22 So LN = MN + LM = 22 + 14= 36

QN = 15.75 is the third answer.

Solve the Triangle if possible
babunello [35]

Answer:

Step-by-step explanation:

A )

a / sinA = c / sinC

sinA = a sinC / c

= 56.2 sin 46.32 / 22.1

= 1.84

The value of sin value of an angle can not be more than 1 so the triangle is not possible .

B )

B  = 180 - ( 32.76 + 21.97 )

B = 125.27

a / sin A = c / sin C

200 / sin 32.76 = c / sin21.97

c = 74.82 / .5411

= 138.27 m

b / sin B = a / sin A

b / sin 125.27 = 200 / sin 32.76

b = 163.28 / .5411

= 301.75 m

C )

Area of triangle = 1/2 ac sinB

= .5 x 7.2 x 3.4 x sin 42

= 8.19 sq ft .
