Answer:

Step-by-step explanation:

Since all sides are half of greater triangle.Then 7 × 2 = 14 is length of greater hypotenuse.

Suppose two triangles with similar conditions

1^2+1^2=2

Hypotenuse=2^1/2

We assume another triangle which is exactly double of previous triangle I.e

2^2+2^2=8

Hypotenuse=2×2^1/2

Which is exactly twice of previous triangle.

Hence proved hyootenuse is double of smaller triangle I.e 14

What is the solution to the equation One-fourth x + 2 = negative StartFraction 5 Over 8 EndFraction x minus 5? X = negative 8 x

Ede4ka [16]

Answer:

$(A)x= -8$

Step-by-step explanation:

One-fourth x + 2 = $\frac{1}{4}x+2$

$\frac{1}{4}x+2=-\frac{5}{8}x-5$

Next, we Expand the Left hand Side by multiplying each term in the bracket by 1/4

$\frac{1}{4}x+\frac{2}{4}=-\frac{5}{8}x-5$

Bringing terms with x to the left Hand Side i.e. collecting like terms

$\frac{1}{4}x+\frac{5}{8}x=-5-2\\\\(\frac{1}{4}+\frac{5}{8})x=-7\\\\\frac{7}{8}x=-7$

On Cross multiplying

7x = -7 X 8

$x=-\dfrac{7*8}{7}\\$

x=-8

∠B

∠Y

Step-by-step explanation:

we know that

In the right triangle ABC

----> opposite side to angle B divided by the adjacent side to angle B

substitute the values

Remember that

If two triangles are similar, then the corresponding sides are proportional and the corresponding angles are congruent

∠A=∠W

∠B=∠Y

∠C=∠Z
