Answer:
x = 26; l = 137; m = 137
Step-by-step explanation:
If the lines are parallel, that means the measurements are too. As such, equal the two expressions together
5x + 7 = 8x - 71
add 71 to both sides
5x + 7 + 71 = 8x - 71 + 71
-71 and +71 cancel each other out
5x + 78 = 8x
subtract 5x from both sides
5x - 5x + 78 = 8x - 5x
5x - 5x cancels each other out
78 = 3x
divide both sides by 3
3x ÷ 3 = 1x which can also be written as just x
78 ÷ 3 = x
26 = x
plug in this x value into both expressions to find variables l and m
l:
5(26) + 7
130 + 7
137
m:
8(26) - 71
208 - 71
137
Answer:
Option (1)
Step-by-step explanation:
The given triangle JKL is an equilateral triangle.
Therefore, all three sides of this triangle will be equal in measure.
Side JK = JL = KL = 48 units
Perpendicular LM drawn to the base JK bisects the base in two equal parts JM and MK.
By applying tangent rule in ΔJML,
tan(∠KJL) =
=
=
Since, Sin(K) =
Sin(60)° =
LM = 24√3
Now, tan(∠KJL) =
=
Therefore, Option (1) will be the answer.
I'm in college, I honestly don't know what it is but I hope you find it!
Answer:
A
Step-by-step explanation:
Hey there!
In this question, it is asking us what table doesn't have a proportional relationship
In table A, there is no seen relation ship between the numbers, columns, or rows
In all of the other tables, the numbers in each column is increasing by a number again and again meaning A is the incorrect table.
