What is the value of x in feet? (Perimeter and area)

Mathematics
1 answer:
babymother [125]3 years ago
4 0

Answer:

x = 71.937 ft or 72 ft

Perimeter = 187 ft

Area of triangle = 1260 ft²

Step-by-step explanation:

Pythagorean Theorem

a^2 + b^2 = c^2

a = 35

b = x

c = 80

35^2 + x^2 = 80^2

x^2 = 5175

x = 71.937 ft or about 72 ft

Perimeter = a  + b + c = 35 + 72 + 80 = 187 ft

Area of triangle =1/2*base*height= 1/2(72)(35) = 1260ft^2

A solid oblique pyramid has an equilateral triangle as a base with an edge length of 4 cm and an area of 12 cm2. What is the vol
Pavel [41]

Solution:

Let me define pyramid first.A pyramid is a Polyhedron , whose base  can be any polygon and it's faces are triangular which meet at a point called vertex.

Volume of Pyramid =  \frac{1}{2}\times{\text{Area of Base}\times{\text{Height}

Side of base which is an equilateral triangle= 4 cm

Area of whole pyramid = 12 square cm

Area of Equilateral triangle having side 4 cm=\frac{\sqrt3}{4}\times(Side)^2=\frac{\sqrt3}{4}\times(4)^2=4 \sqrt3 cm²

So, Area of three triangle which are faces of pyramid = (12 - 4 √3)cm²

Area of triangle = \frac{1}{2} \times (Base)\times(Height)

12 - 4 √3= \frac{1}{2} \times (4)\times(Height)

Height =\frac{12-4\sqrt3}{2}

Height=(6-2√3) cm

Volume of pyramid = Area of Equilateral triangle which is it's Base × Height of Pyramid

          =4√3 × (6-2√3) cm³

           =(24 √3 -24)

           = 24 (1.732-1)

          =24 × 0.732

          =17.568 cm³

A circle has a central angle measuring StartFraction 7 pi Over 10 EndFraction radians that intersects an arc of length 33 cm. Wh
cupoosta [38]

The radius of the given circle with a central angle of 7π/10 and arc length of 33cm is 15cm.

It is given that

The central angle of the given circle = 7π/10 radians

Length of arc = 33cm

<h3>What is the formula for arc length?</h3>

Arc length = central angle* radius

From the above formula

Radius = Arc length/Central Angle

Radius = \frac{33}{(7\pi)/10 }

Radius = 15cm

Therefore, radius of the given circle is 15cm.
