This is for 75 points and brainlyest if you can help ​
hoa [83]

Answer:

(3x - 5°) = 52°

Step-by-step explanation:

Formula we use,

→ A + B + C + D + E = 540°

Then the value of x will be,

→ A + B + C + D + E = 540°

→ (6x + 25°) + (5x + 10°) + (3x - 5°) + (5x + 10°) + (6x + 25°) = 540°

→ (6x + 5x + 3x + 5x + 6x) + (25° + 10° - 5° + 10° + 25°) = 540°

→ 25x + 65° = 540°

→ 25x = 540° - 65°

→ 25x = 475°

→ x = 475/25

→ [ x = 19° ]

The value of angle (3x - 5°) will be,

→ (3x - 5°)

→ (3 × 19) - 5°

→ 57° - 5°

→ [ 52° ]

Hence, value of angle (3x - 5°) is 52°.
