Maybe using a protractor might help. But know that a straight angle equals 180. I don't really understand it. But use the <span>Pythagorean Theorem so a^2+B^2=c^2</span>

Answer: y = x + 1
</h2>
Step-by-step explanation:
For us to write the equation for this line, we need to (1) find the slope of the line, and (2) use one of the points to write an equation:
The question gives us two points, (3, 4) and (-4,-3), from which we can find the slope and later the equation of the line.
<u>Finding the Slope</u>
The slope of the line (m) = (y₂ - y₁) ÷ (x₂ - x₁)
= (4 - (- 3)) ÷ (3 - (-4))
= 1
<u>Finding the Equation</u>
We can now use the point-slope form (y - y₁) = m(x - x₁)) to write the equation for this line:
⇒ y - (-3) = 1 (x - (-4))
y + 3 = (x + 4)
we could also transform this into the slope-intercept form ( y = mx + c)
since y + 3 = (x + 4)
⇒ y = x + 1

Answer:
A. meter stick
Step-by-step explanation:
The other answers do not make sense.
B is used to measure liquids.
C is used to measure weight/mass
D is used to measure the ingredients needed for a recipe, usually cooking.
Answer:
see below.
Step-by-step explanation:
The two lines are parallel with different y intercepts. That means they never intersect. The solution to the system of equations is where they intersect. This means there is no solution to the system of equations.
Answer:
angle B: 39
AC: 7.288
AB: 11.58
(note: you cut off the part about rounding so make sure that it's rounded correctly before you put in your answer)
Step-by-step explanation:
To solve this we will use SOH, CAH, TOA
we have the angle and the one opposite to it which means we can use either SOH or TOA
let's use TOA
tan(51)=(9/x)
x= 7.288
We can now use pahtagaryous theroem to solve for the hyptonouse
we have
9²+7.288²=C²
C=11.58
Finally, to find angle B we will recall that the angles of a triangle must add to 180.
51+90+a=180
a=39
