Answer:
x = 10
Step-by-step explanation:
It's given in the question that both the traingles JCD & JKL are similar. So their ratio of corresponding similar sides will be proportional to each other.
[tex] = > \frac{JD}{JL} = \frac{JC}{JK} = \frac{DC}{LK} [/tex]
[tex] = > \frac{15}{50} = \frac{8 + x}{60} = \frac{DC}{LK} [/tex]
[tex] = > \frac{15}{50} = \frac{8 + x}{60} [/tex]
[tex] = > 8 + x = \frac{15 \times 60}{50} = 18[/tex]
[tex] = > x = 18 - 8 = 10[/tex]

Answers
Answer:
acute maybe
Step-by-step explanation:
The given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.
What is the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees.
Given that:-
In AABC AB = 3x - 2, BC=x+4, and AC = 7. Also AB = BC
We know that AB = BC
3x - 2 = x + 4
3x = x + 4 + 2
3x = x + 6
2x = 6
x = 3
AB = 3x - 2 = 3(3) - 2 = 7
BC = x + 4 = 3 + 4 = 7
All three sides are equal so the triangle is an equilateral triangle. Hence given ΔABC is an equilateral triangle because all the sides are equal. The term which does not describe the ΔABC is obtuse option D is correct.

x – 7y = –11
5x + 2y = -18
Answers
Answer:
hope this help you
Step-by-step explanation:
Simplifying
X + -7y = -11
Solving
X + -7y = -11
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '7y' to each side of the equation.
X + -7y + 7y = -11 + 7y
Combine like terms: -7y + 7y = 0
X = -11 + 7y
Simplifying
X = -11 + 7y
------------------------------------------------------------------------------------------------------------
Solving
5x + 2y = -18
Solving for variable 'x'.
Add '-2y' to each side of the equation.
5x + 2y + -2y = -18 + -2y
Combine like terms: 2y + -2y = 0
5x = -18 + -2y
Divide each side by '5'.
x = -3.6 + -0.4y
Simplifying
x = -3.6 + -0.4y
