A and a' are vertical angles, therefore a' = a

We know: The sum of the measures of triangle is always 180°.

Therefore: a' + b + d = 180° → d = 180° - a - b.

d and c are adjacent angles, therefore d + c = 180°

substitute

180° - a - b+ c = 180°    |-180°
-a - b + c = 0    |+a  |+b
c = a + b

Find the nonpermissible replacement for y in the expression y-3/y+3
Nastasia [14]

Answer:

The nonpermissible replacement of the variable y is -3

Step-by-step explanation:

The nonpermissible replacement of the variable in a certain expression is the value of the variable that will make the denominator of the expression zero.

The expression \dfrac{y-3}{y+3} has the denominator y+3.

This denominator cannot be equal zero, thus,

y+3\neq 0,\\ \\y\neq -3.

A force of 61 N is applied to an area of 750 cm2. Calculate the pressure in N/m2. Give your answer to the nearest integer
Dafna11 [192]

Answer:

  813 N/m²

Step-by-step explanation:

The units of pressure tell you it is found by dividing force by area. Here, we need to convert the units of the given area so we can express the pressure appropriately.

__

  pressure = force / area

  pressure = (61 N)/(750 cm² × ((1 m)/(100 cm))²) = (61 N)/(0.0750 m²)

  pressure ≈ 813 N/m²
