a.
$2^2+3^2=(\sqrt{13})^2 \\
4+9=13 \\
13=13 \\ true$

b.
$2^2+2^2=4^2 \\
4+4=16 \\
8=16 \\
not \ true$

Can someone help me out?

Lera25 [3.4K]

Answer:

so basically

the area of the square; (5cm)^2 = 25cm^5

the area of the triangle; (4cm.5cm)/2 = 10cm^2

which means that r = √25cm^2/10cm^2 = √25/10 cm^2 or √10/25 cm^2

english is not my first language so i do not know what combined means but if u explain a little more i will try to help u

-> ok edit edit;

1cm/5in. = r

5cm => 25in.

z^2= area of a square so

25in.25in= 625 in^2

4cm => 20in.

5cm => 25in.

h.b/2 = area of a triangle so

20in.25in./2 = 250in.^2

250in.^2 + 625in.^2 = 875in.^2

so answer B

The face of a triangular shaped guitar has an area of 52 in.² and a height of 13 inches. Write an equation to find the length of

Neko [114]

Area of a triangle can be calculated as:

Area = 0.5 x Base x Height

Area is given to be 52 in²
Height is 13 inches.
We are to find the base b of the triangular shaped guitar.

Using the values in above formula, we get:

$52=0.5(13)(b) \\ \\ 
b= \frac{52}{0.5(13)} \\ \\ 
b=8$

Thus the base of triangular shaped guitar will be 8 inches.
