Answer:

A = $11.75

E = $15.5

J = $21.75

Step-by-step explanation:

J = E + 6.25

A = J - 10

A + E + J = 49

(Apply Algebra & Simultaneous Equations)

Hence:

J -10 + E + J = 49

2J -10 + E = 49

2J + E = 59

2(E+6.25) + E = 59

2E + 12.5 + E = 59

3E = 46.5

E = $15.5

J = 15.5 + 6.25

J = $21.75

A = 21.75 - 10

A = $11.75

OLga [1]

Answer:

  • m∠J = 76°
  • m∠K = 65°

Step-by-step explanation:

The sum of angle measures is ...

  (7x +13)° +(83 -2x)° = 141°

  5x +96 = 141 . . . . . collect terms, divide by °

  5x = 45 . . . . . . . . . subtract 96

  x = 9 . . . . . . . . . . . divide by 5

  7x +13 = 7·9 +13 = 76 . . . . . find m∠J

  m∠J = 76°

  m∠K = 141° -76°

  m∠K = 65°

WILL GIVE BRAINLEST!!! solve the triangle and answers to the nearest tenth.
sineoko [7]

Answer:

Angle A is 29 degress Angle B is 61 Angle C is 90

Side AB is 5.8 Side BC is 2.8 and  Side AC is 5.1

Step-by-step explanation:

Angle A is found using triangle interior theorem.

I found side AC by using law of sines

b/sin b= c/sin c

x/sin 61= 5.8/sin 90( which equal 1)

x=5.1

I found side BC by using pythagoren theorem.

a^2 + b^2=c^2

5.1^2+ b^2=5.8^2

26.01+b^2=36.64

b^2=7.63

b=approx 2.8.
