In the accompanying figure. ABCD is a square. LaTeX: AB=5x-10 A B = 5 x − 10 and LaTeX: BC=2x+20. B C = 2 x + 20. Find the value
jek_recluse [69]
Answer:
x = 10

Explanation:
A square is a quadrilateral in which all sides are equal.

We are given that:
ABCD is a square
AB = 5x - 10
BC = 2x + 20

Since we're talking about a square, therefore:
AB = BC
5x - 10 = 2x + 20
5x - 2x = 20 + 10
3x = 30
x = 30/3
x = 10

Now, we can check our solution:
AB = 5(10) - 10 = 40 units
BC = 2(10) + 20 = 40 units
We can see that both sides are equal

Hope this helps :)

Can I get some help abs an easy explanation pls

we are given the following triangles:

We are asked to determine the value of "y". To do that we will use the tangent of 25:

\tan 25=\frac{y}{x}

We solve for "y" by multiplying both sides by "x":

x\tan 25=y

Now, we take the tangent of 15:

\tan 15=\frac{y}{30+x}

Now, we solve for "y" by multiplying both sides by the denominator:

(30+x)\tan 15=y

Now, we set both values of "y" equal, we get:

x\tan 25=(30+x)\tan 15

now, we solve for "x". First, we apply the distributive property on the right side:

x\tan 25=30\tan 15+x\tan 15

Now, we substract
