Alexandra [31]

Answer: 87^{\circ}

Step-by-step explanation:

Because an angle inscribed in a semicircle is a right angle, \angle B=90^{\circ}

So, as angles in a triangle add to 180 degrees, \angle A=180^{\circ}-90^{\circ}-3^{\circ}=\boxed{87^{\circ}}

The variable z varies jointly with the square of x and inversely with y. Z = 4.4 when x = 3 and y =2. Find an equation that rela
Mrac [35]

Answer:

z = 0.9778x^2 / y.

Step-by-step explanation:

When z varies with the square of x the equation is z = kx^2 where k = a constant.

If it also varies inversely with y the equation is z = kx^2/y.

When z = 4.4 , x = 3 and y = 2 we have:-

4.4 = k * 3^2 / 2

Multiplying by 2:

8.8 = 9k

k = 8.8 / 9  

= 0.9778.

So the required formula is z = 0.9778x^2 / y.
