Answer:
Answer 44
Step-by-step explanation:
I'll do some of it. You can supply some of the vocabulary.
<Q = 56 degrees The triangle is isosceles.
<PRQ = 180 - 56 - 56 All triangles have 180 degrees.
<PRQ = 68 Do the subtraction
<PRQ = <SRT Why is this so? You have the term.
<TRS = 68 degrees The reason is the same as the last part.
<T = <RST The triangle is isosceles (2 equal angles)
<T = 68 Two equal angles = the same degrees
S = 180 - <T - < RST S is the left over from the 2 equal angles.
S = 180 - 68 + 68 Substitute.
S = 44
Answer:
y = - 
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (- 4.5, 0 ) ← coordinates of intercepts
m = 
= 
= 
= -
The line crosses the y- axis at (0, - 3 ) ⇒ c = - 3
y = - x - 3 ← equation of line
Answer:
-1.5x - y + 7 = 0
Step-by-step explanation:
The formula for point slope form is y-yA = m(x - xA).
y - (-2) = -1.5(x + 6)
y + 2 = -1.5x + 9
y = -1.5x + 9 - 2
y = -1.5x + 7
-1.5x - y + 7 = 0 is the point slope form.
Answer:
5 1/2 x
Step-by-step explanation:
You divide 1444 kilometers by 110 kilometers to get x cm.
1444/110 = <span>13.127
x = 13.127 cm
