Question

Can someone pls help

Answer 1

x = 35

Explanation:

Sum of angles of triangle = 180°

• 60 + 60 + 4x - 80 = 180
• 40 + 4x = 180
• 4x = 140
• x = 140/4
• x = 35°

Answer 2

❒ Required Solution:

• We are here to find the three angles with the help of the angle sum property (Sum of the angles of a triangle = 180°). So, using this property we can find all the angles.

❍ According to the question :

`\\ \tt \implies \: 60{}^( \circ) + 60{}^( \circ) +(4x - 80) {}^( \circ) = 180{}^( \circ) \\ \\ \\ \implies \tt \: 120{}^( \circ) - 80{}^( \circ) + 4x = 180{}^( \circ) \: \: \: \: \: \: \\ \\ \\ \implies \tt 40{}^( \circ) + 4x = 180{}^( \circ) \: \: \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: 4x = 180{}^( \circ) - 140{}^( \circ) \: \: \: \: \: \: \\ \\ \\ \tt \implies \: 4x = 140{}^( \circ) \: \: \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \implies \tt \: x = (140)/(4) \: \: \: \: \: \: \: \: \: \: \\ \\ \\ \tt \implies \: { \boxed{ \mathfrak{ \pmb{ \pink{x = 35}}}}} \bigstar \\ \\ \\`
