Answer 1

Answer:

$we \: know \: \\ x + 34 + x + 15 + x = 180 \\ 3x + 49 = 180 \\ 3x = 131 \\ x = 42.3$

hope it helps you ✅✅✅

Answer 2

Answer:

The angles are 77.6°, 58.6° and 43.6°.

Step-by-step explanation:

The given angles are on a straight line. Which means the sum of all three is 180°

• First angle = x + 34
• Second angle = x + 15
• Third angle = x

$\longrightarrow$ (x + 34) + (x + 15) + x = 180°

$\longrightarrow$ 3x + 39 = 180

$\longrightarrow$ 3x = 180 - 39

$\longrightarrow$ 3x = 131

$\longrightarrow$ x = 131/3

$\longrightarrow$ x = 43.6

Value of x = 43.6°

Third angle = 43.6°

★ First angle :

$\longrightarrow$ x + 34

$\longrightarrow$ 77.6°

★ Second angle :

$\longrightarrow$ x + 15

$\longrightarrow$ 58.6°

Therefore, the angles are 77.6°, 58.6° and 43.6°.
