The perimeters of two similar triangles are 25 cm and 15 cm respectively. If one side of the first

Vanyuwa [196]

Answer:

5.4cm

Step-by-step explanation:

In similar triangles, the perimeter of the triangles will be in the ratio of their corresponding sides.

The ratio of their perimeter is

perimeterofΔ2 15

--------------------- = -------------

perimeterofΔ1 25

So, the side of triangle 2 will be

9 * 15 15

---------------- = --------------

sideofΔ2 25

⟹side of Δ2= 25 / 9∗15 =5.4.

JNZ~ KOA. Find the unknown measures

shepuryov [24]

Answer:

Step-by-step explanation:

If ΔJNZ and ΔKOA are similar, then corresponding sides are in proportion and corresponding angles are congruent.

We have the proportion:

$\dfrac{JN}{KO}=\dfrac{NZ}{OA}=\dfrac{ZJ}{AK}$

and equations:

$m\angle N=m\angle O=90^o\\m\angle Z=m\angle A=28^o\\m\angle J=m\angle K=62^o$

We have:

$JN=8\ in,\ NZ=15\ in,\ KO=4\ in,\ AK=x\ in,\ ZJ=y\ in$

For y we must use the Pythagorean theorem:

$ZJ^2=JN^2+NZ^2\\\\y^2=8^2+15^2\\\\y^2=64+225\\\\y^2=289\to y=\sqrt{289}\\\\y=17\ in$

$\dfrac{JN}{KO}=\dfrac{ZJ}{AK}\to\dfrac{8}{4}=\dfrac{17}{x}$ <em>cross multiply</em>

$8x=(4)(17)$

$8x=68$ <em>divide both sides by 8</em>

$x=8.5\ in$

Answer:

y -4 = -2(x -(-11))

Step-by-step explanation:

The point slope formula is ...

y -k = m(x -h) . . . . . line with slope m through point (h, k)

So, the boxes in order from left to right are k, m, h.

The problem statement tells you the point is (-11, 4), so h = -11, k = 4. It also tells you the slope is -2, so m = -2.

Putting these numbers in the required order, we have k = 4, m = -2, h = -11 and the equation of the line is ...

$y-\boxed{4}=\boxed{-2}(x-\boxed{-11})$

Anyone know how to find the area with the missing hypotenuse? Thank you!!!

suter [353]

Answer:

$15 {cm}^{2}$

Step-by-step explanation:

There's no need of hypotenuse for finding area of the triangle. To find the area of a triangle ,

Formula is = $\frac{1}{2} \times base \times height$

Base of the triangle = 10 cm

Height of the traingle = 3 cm

Area of the triangle = $\frac{1}{2} \times 10 \times 3 = 15 {cm}^{2}$
