Mathematics
1 answer:
AveGali [126]2 years ago
6 0

Step-by-step explanation:

Here in the given figure the value of x will be 70° ( being alternative angle )

x = 70°

Now...

y = 60° ( being corresponding angle )

Now...

60° + 70° + z = 180° ( the sum of interior angle of triangle is 180°

z = 180° - 130°

z = 50° ..

...

10 POINTS<br> Find the surface area of the regular pyramid. Round to the nearest tenth if necessary.
NNADVOKAT [17]

Answer:

SA=234.8\ yd^2

Step-by-step explanation:

we know that

The surface area of the regular pyramid is equal to the area of the triangular base plus the area of its three triangular lateral faces

step 1

Find the area of the triangular base

we know that

The triangular base is an equilateral triangle

so

The area applying the law of sines is equal to

A=\frac{1}{2}(14^2)sin(60^o)

A=\frac{1}{2}(196)\frac{\sqrt{3}}{2}

A=49\sqrt{3}=84.87\ yd^2            

step 2

Find the area of its three triangular lateral faces

A=3[\frac{1}{2}bh]

we have

b=14\ yd

Find the height of triangles

Applying the Pythagorean Theorem

10^2=(14/2)^2+h^2

solve for h

100=49+h^2

h^2=100-49

h=\sqrt{51}\ yd

substitute

A=3[\frac{1}{2}(14)\sqrt{51}]      

A=149.97\ yd^2

step 3

Find the surface area

Adds the areas

SA=84.87+149.97=234.84\ yd^2

Round to the nearest tenth

SA=234.8\ yd^2

The sum of three consecutive even integers is 72. Let x represent the first integer x+2 represent the second integer and x+4 rep
satela [25.4K]

72 = x + x+2 + x+4

72 = 3x+6

66 = 3x

x = 66/3 = 22

1st number = 22

2nd number = 22+2 = 24

3rd number = 22+4 = 26
