Answer:

132 ft²

Step-by-step explanation:

If you combine the two triangles of the 'roof', you get a rectangle of 6x5.5=33, where 6 is calculated as 15-9 and 5.5 comes from 11/2.

Add to that the area of the rest of the 'house', which is a rectangle of 9x11=99

and the total area is 63+99 = 132.

JNZ~ KOA. Find the unknown measures

shepuryov [24]

Answer:

<h2>x = 8.5in, y = 17in, r = 28°, s = 62°</h2>

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>

$x=8.5\ in$

If w+ -4 2/5= 1/10 what does w equal

Nesterboy [21]

Answer:

Step-by-step explanation:

w+ -4 2/5= 1/10

W = 1/10 + 4 2/5

W = 1/10 + 22/5

W = (1 + 44)/10

W = 45/10

W = 9/2

W = 4 1/2
