Answer:

measure of <DFH=56

Step-by-step explanation:

The two triangles are similar, so their angles are the same, but their lengths are different.

If their angles are the same, then 98-6x=63-x.

98-6x=63-x (subtract: 98-63)

35-6x=-x (add 6x-x)

35=5x (divide by 5)

7=x (Then make sure you answer the question and put x in 63-x.)

63-(7)=56

Answer:

5 + 2.5 > 4 feets

4 + 5 > 2.5 feets

2.5 + 4 > 5 feets

Step-by-step explanation:

The triangle states that :

The sum of any 2 sides of a triangle must be greater than the third side

Side Given are :

5feets ; 2.5 feets ; 4 feets

In other to obey the triangle rule :

5 + 2.5 > 4 feets

4 + 5 > 2.5 feets

2.5 + 4 > 5 feets

Answer:

4 weeks : 5 books

8 weeks : 10 books

Step-by-step explanation:

alright so she is reading at a rate of 1.25 books per week, we know this becasue we can divide 15/12 which is equal to 1.25. Know we know the rate we can just multiply the rate by the number of weeks, so 4 * 1.25 = 5, and 8 * 1.25 = 10.

This net can be folded to make a square pyramid. what is the surface area of the pyramid

givi [52]

Answer:

$85in^2$

Step-by-step explanation:

to find the surface area we need to find the followng areas:

area of the square

area of a triangle and multiply it by 4 (because there are 4 triangles)

And once we have those areas, we add them to find the surface area.

Area of the square:

the formula to find the area of a square is:

$a_{square}=l^2$

where $l$ is the length of the side: $l=5in$

thus the area of the square is:

$a_{square}=(5in)^2$

$a_{square}=25in^2$

Area of the triangles:

the are of 1 triangle is given by

$a_{triangle} =\frac{b*h}{2}$

where $b$ is the base of the triangle: $b=5in$ (the base of the triangle is the side of the square)

and $h$ is the height of the triangle: $h=6in$

thus, the area of 1 triangle is:

$a_{triangle} =\frac{(5in)*(6in)}{2}$

$a_{triangle} =\frac{30in^2}{2}$

$a_{triangle} =15in^2$

the area of the 4 triangles is (we multiply by 4):

$a_{4-triangles}=4(15in^2)$

$a_{4-triangles}=60in^2$

finally we add the area of the square and the area of the 4 triangles to find the total surface area:

$Surface=25in^2+60in^2$

$Surface=85in^2$
