a)3x+33=90, x=19 b)52, 38

Step-by-step explanation:

a)

so x+33+2x=90

which simplifies to 3x+33=90

Now we need to solve that equation.

3x+33=90

x+11=30

x=19

b)

angle 1 is x+33.

19+33=53

angle 2 is 2x

19*2=38

Part A: (x+33) + (2x) = 90

Part B: mAngle 1= 52, mAngle 2= 38

Step-by-step explanation:

Part A:

To write an equation, we first must understand what we are trying to describe/equal to. In the figure, we can see a box in the bottom left corner. This signifies that the angle is a right angle, which equals to 90 degrees.

In the directions, it gives us the measurement of the two angles that make up that 90 degree angle, which is angle 1 and angle 2.

Angle 1 equals to x+33 and angle 2 equals to 2x.

Thus, we can say (x+33) + (2x) equals to 90 degrees.

Part B:

Now, we must solve for the angles. Simply, we must find the value of "x."

To do that, we add like terms on both sides of the equation:

(x+33) + (2x) = 90 becomes 3x + 33 = 90

There are two ways you can proceed from here: factor and solve, or simply the old fashioned way: elimination.

Factor and solve:

3x + 33 = 90 becomes 3(x+11)=3(30). I simply factored the LCD (largest common denominator) from both sides. If we multiply it out, we'll return to 3x + 33 = 90 We then proceed to divide both sides by three, giving us x+11=30. x equals 19.

Elimination:

3x + 33 = 90 becomes 3x=57. I simply subtracted 33 from both sides. Then, isolate x by dividing by three, and x equals 19.

We aren't done just yet. Now, since we know what x equals, we must substitute 19 for x in angle 1 and angle 2.

(x+33) + (2x) = 90

(19+33) + [2(19)] = 90

52 + 38 = 90

So, measure of angle 1 is 52, and measure of angle 2 is 38.

Let me know if you have any questions.  

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is
