Answer:
13.9mm
Step-by-step explanation:
short story, pythagorean theorem a²+b²=c²
a=13.5
b=3.2
c=?
13.5² = 182.25
3.2² = 10.24
c² = 192.49
c = 13.8740765458
round to 1 decimal place c = 13.9
Answer:
The answer to your question is: n = 95°
Step-by-step explanation:
The sum of the suplementary angles equals 180°
Then
121 + x = 180
x = 180 - 121
x = 59°
144 + y = 180
y = 180 - 144
y = 36°
The sum of the internal angles in a triangle equals 180°
x + y + z = 180
59 + 36 + z = 180
z = 180 - 59 - 36
z = 85
Finally
n + 85 = 180
n = 180 - 85
n = 95°
Answer:
r = 19
Step-by-step explanation:
calculate the slope using the slope formula and equate to 4
m =
with (x₁, y₁ ) = (- 7, 3 ) and (x₂, y₂ ) = (- 3, r )
m = = = , then
= 4 ( multiply both sides by 4 )
r - 3 = 16 ( add 3 to both sides )
r = 19

It's SSS, gib me brainliest if u can. :)
Step-by-step explanation:
Answer:
Hence, the correct option is;
They are parallel because they have the same slope of -2
Step-by-step explanation:
Here we have;
AB falls on the line 6x + 3y = 9..........................(1)
CD falls on the line 4x + 2y = 8..........................(2)
Therefore, for equation (1),
3y = 9 - 6x which gives;
y = -2x + 3
for equation (2),
2y = 8 - 4x which gives;
y = -2x + 4
The equation of a straight line is y = m·x + c
Where:
m = Slope
c = Intercept
Hence, since, by comparison to the equation of a straight line, both lines have the same slope of -2, but different intercept, we have that both lines are parallel
Hence, the correct option is;
They are parallel because they have the same slope of -2.
