Answer:

BC ≈ 20.5 in

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos35° = $\frac{adjacent}{hypotenuse}$ = $\frac{BC}{AB}$ = $\frac{BC}{25}$ ( multiply both sides by 25 )

25 × cos35° = BC , thus

BC ≈ 20.5 in ( to the nearest tenth )

What is the volume of this cuboid? Please help me!!!?!

Snowcat [4.5K]

The formula of a volume of a cuboid:

$V=lwh$

l - length

w - width

h - height

We have:

l = (x + 4) cm

w = (x + 1) cm

h = 3 cm

Substitute:

$V=(x+4)(x+1)(3)$ use distributive property

$V=(x+4)(3x+3)$

$V=(x)(3x)+(x)(3)+(4)(3x)+(4)(3)$

$V=3x^2+3x+12x+12$ combine like terms

$\boxed{V=3x^2+15x+12}$
