Which pairs of triangles are similar? Check all that

Mandarinka [93]

Answer:

JKL and ABC

DEF and GHI

Step-by-step explanation:

we know that

If two triangles are similar, then the ratio of its corresponding angles is proportional and its corresponding angles are congruent

In this problem

1) triangles JKL and ABC are similar

because

$\frac{KL}{BC} =\frac{JL}{AC}$

substitute the given values

$\frac{10}{20} =\frac{7}{14}$

Simplify

$\frac{1}{2} =\frac{1}{2}$ ---> is true

therefore

The ratio of the corresponding sides is proportional

That means----> The triangles are similar

2) triangles DEF and GHI are similar

because

$\frac{HI}{EF} =\frac{GI}{DF}$

substitute the given values

$\frac{15}{10} =\frac{12}{8}$

Simplify

$1.5=1.5$ ---> is true

therefore

The ratio of the corresponding sides is proportional

That means----> The triangles are similar

A pyramid has a square base and a height of 6 ft. The volume of the pyramid is 162 ft^3. Let s be the length of a side of the py

geniusboy [140]

Answer:

$(a)s^2\\(b)162=2s^2\\(c)s=9$ ft$

Step-by-step explanation:

(a)Base Area

Side length of square base=s

Area of a Square of side length s= $s^2$ ft^2$

(b)

Height =6 ft
Volume= $162 $ ft^3.$

Volume of a Pyramid $=\frac{1}{3}X$Base Area X Height$

Substituting the given values, we have:

$162=\frac{1}{3}Xs^2 X 6\\\\162=2s^2$

(c)Solving the equation derived from (b)

$162=2s^2\\$Divide both sides by 2\\s^2=81\\s^2=9^2\\s=9$ ft$

Solving this equation shows that s =9 ft.
