In δabc, ∠a measures 132° and the values of b and a are 36 and 70, respectively. find the remaining measurements of the triangle, and round your answers to the nearest tenth. ∠b = 82.2°, ∠c = 62.8°, c = 40.6 ∠b = 82.2°, ∠c = 62.8°, c = 30 ∠b = 22.5°, ∠c = 25.5°, c = 40.6 ∠b = 22.5°, ∠c = 25.5°, c = 30

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -
