Sagot :

Answer:

128

Step-by-step explanation:

Angles on a straight line always add up to 180°

We can use this fact to work out x

we do the following:

(x + 3)+49= 180

take away 49 from both sides

180-49=131

so (x + 3)= 131

take away 3 from both sides

and you are left with:

x=128

hope this helps!

Answer:

The value of x is 128°

Step-by-step explanation:

The sum of all angles lies a straight line is 180°

Therefore, (x + 3)° + 49 = 180°

Open all the bracket on LHS.

→ x° + 3° + 49°= 180°

→ x° + 52° = 180°

Shift constant from LHS to RHS, changing it's sign.

→ x° = 180° - 52°

→ x° = 128°

Therefore, x = 128°

The given angle are substitute x = 128°

(x + 30)° = (128 + 30)° = 158°

and

49°

Answer: Hence, the measurement of angles are 158° and 49°.

Verification:

(x + 3)° + 49° = 180°

→ (128 + 3)° + 49° = 180°

→ (131)° + 49° = 180°

→ 131° + 49° = 180°

→ 180° = 180°

LHS = RHS

Hence, verified.
