Answers

Answer:

The measure of angle two is 47 degrees (first triangle), and the measure of angle four is 42 degrees (second angle)

Step-by-step explanation:

Remember that all triangles have a full measurement of 180 degees.

Since measure one is is 65 degrees, we need to add 65 and 68, which is 133 degrees.

Now we subtract 180 - 133 = 47.

The measure of angle two is 47 degrees.

Since the angle of measure three is 89 degrees, we need to add 89 + 49, which is 138 degrees.

180 - 138 = 42.

Make x the subject of the formula y=9ax-4b
helppp

Answers

Answer:

take out the a with an equation

The solution of x is y+4b/9a for equation y=9ax-4b

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

The given equation is y=9ax-4b

y equal to nine times of  and x minus four times of b.

We need to solve for x

Add 4b on both sides

y+4b=9ax-4b+4b

y+4b=9ax

Divide both sides by 9a to separate x on RHS

y+4b/9a=x

Hence the solution of x is y+4b/9a for equation y=9ax-4b
