I need help please sorry it’s like that a camera and a screen don’t work good together

The value of x = 20.05

Step-by-step explanation:

As we know that the sum of the angles in a triangle is 180°.

From the diagram, we can say that the sum of the angles A, B, and C must be 180°.

so the equation of the sum of the angles of a triangle will be:

As

Substituting the values in the equation of the sum of the angles of a triangle to find the value of x.

            ∵

Subtract from both sides

Therefore, the value of x = 20.05

VERIFICATION:

b.) 160 miles on a 5 gallons car

step-by-step explanation:

240/10=24 miles/gallon

160/5=32 miles/gallon

30/1=30 miles/gallon

168/6= 28 miles/gallon

32 miles/gallon is the most amount, so this is the best.

i think this could be a possible answer (1 / 84) -1

good luck! : d
