8. Since A F is perpendicular to J K, you know angles J A F and K A F are congruent (both are right angles). Since A F bisects J K, you know the lengths of J A and K A are the same. Side A F is incident to both triangles, and of course the lengths A F = A F. So we have two side-angle-side triangles, and by the SAS postulate we have triangles J F K and K F A congruent to one another.

9. Yes. The corresponding sides in both triangles have the same lengths. (S K to K F; S J to F J; J K to itself) The claim then follows from the SSS postulate.

What is the solution set to.the following system?{x+y=4, x^2+y^2=16}
olganol [36]

Answer:

x= 3.47 or x= -4.47 ,  y= 0.53 or y= 8.47

Step-by-step explanation:

quadratic equation:

x^2 + y^2 = 16

(-b± √b^2 - 4*a*c) /2

(-1 ± √ 1-4*1*16)/2

(-1 ± 3√7)/2

(-1 ± 7.94)/2

(-1 + 7.94 )/2 or (-1-7.94)/2

x= 3.47 or -4.47

therefore:

x+y = 4

3.47 + y = 4     or -4.47 + y = 4

y = 4-3.47       or y = 4+ 4.47

y= 0.53   or y = 8.47

seorang tukang kayu akan memotong tripleks berukuran 3,5 meter x 3,5 meter. tentukan luas dan keliling tripleks tersebut​
g100num [7]

Answer:

Part 1) A=12.25\ m^2

Part 2) P=14\ m

Step-by-step explanation:

<u><em>The question in English is</em></u>

A carpenter will cut plywood measuring 3.5 meters x 3.5 meters. Determine the area and perimeter of the plywood.

Part 1) Determine the area

we know that

The area of a square is given by the formula

A=b^2

where

b is the length side

we have

b=3.5\ m

substitute

A=3.5^2=12.25\ m^2

Part 2) Determine the perimeter

we know that

The perimeter of a square is given by the formula

P=4b

where

b is the length side

we have

b=3.5\ m

substitute

P=4(3.5)=14\ m
