1. If Salwa constructs a triangle using her protractor, and the first twoangles she constructed were 55° and 105°, what will the third angle be
when she is done?
80°
30°
20°
55

Answers

Answer 1
Answer:

Answer: 20°

Step-by-step explanation:

Hi, to answer this question we have to analyze the information given:

Angle 1 = 55°

Angle 2 = 105°

The sum of the three interior angles of a triangle is always 180°.

So:

180 = 55+105 + x

Where x is the missing angle.

Solving for x:

180-55-105 =x

20°=x

The equation shows the relationship between x and y:y = 7x + 2

What is the slope of the equation?


-7

7

Answers

y=mx+b is the formula.
m is the slope and b is the y-intercept.

y-intercept is when x is 0 and x-intercept is when y is 0. So if x is 0, y=m(0)+b which is y=b. So on the graph y will be b when x is 0.

So in y=7x+2, 7 is the slope and 2 is the y-intercept.

\sf\ Slope:\ {\boxed{7}


y={\underbrace{m}x+{\underbrace{b}
\sf\~~~~SLOPE~~~~~Y-INTERCEPT
Below is the slope intercept form:
y = mx + b

where: m = slope; b = y-intercept.

Using the above format, 

y = 7x + 2

m = 7 ; b = 2

The slope of the equation is 7.
The y-intercept of the equation is 2.
