The diagrams shows a 3cm x 5cm x 4cm cuboid.
Vera_Pavlovna [14]

Answer:

a) 5.83 cm

b) 34.45°

Step-by-step explanation:

a) From Pythagoras theorem of right triangles, given right triangle ABC:

AB² + BC² = AC²

Therefore:

AC² = 5² + 3²

AC² = 25 + 9 = 34

AC = √34

AC = 5.83 cm

b) From triangle ACD, AC = 5.83 cm, AD = 4 cm and ∠A = 90°.  

From Pythagoras theorem of right triangles, given right triangle ACD:

AD² + AC² = DC²

Therefore:

DC² = 5.83² + 4²

DC² = 34 + 16 = 50

DC = √50

DC = 7.07 cm

Let ∠ACD be x. Therefore using sine rule:

\frac{4}{sin(x)}=\frac{7.07}{sin(90)} \\ sin(x)=\frac{4*sin(90))}{7.07}=0.5657\\ x=sin^{-1}(0.5657)\\x=34.45^o

Choose ALL answers that describe the quadrilateral VWXYVWXY if VW = 55VW=55, WX = 67WX=67, XY = 45XY=45, YV = 33YV=33, \text{m}\
frozen [14]

The quadrilateral VWXY is a trapezoid.

<h3>What is a quadrilateral?</h3>

A quadrilateral is a polygon with four sides and four angles. Types of quadrilaterals are parallelogram, rectangle, rhombus, square and trapezoid.

A Trapezoid is a quadrilateral with a pair of opposite parallel sides.

Given a quadrilateral VWXY, WX = 67, XY = 45, YV = 33, VW = 55, and all the angles are different, hence:

The quadrilateral VWXY is a trapezoid.

Help please, i'll give the crown thing if I can
Wewaii [24]

Answer:

i) p = 4

ii) p = 8

iii) p = 12

Step-by-step explanation:

Here, we need to understand the initial relation

Mathematically, we have this as;

2.79 * p = c

So let us calculate the value of p for each value of c

i) 2.79p = 11.16

p = 11.16/2.79

p = 4

ii) 2.79p = 22.32

p = 22.32/2.79

p = 8

iii) 2.79p = 33.48

p = 33.48/2.79 = 12

Green: 3

Black: 3

Blue: 1

Red: 4
