A triangle has sides with length of 11 feet 12 feet and 13 feet. Is it a right triangle

Answers

Answer:

No

Step-by-step explanation:

It will be a right triangle if it follows Pyhthagoras Theorem . Where the sum of squares of two smaller sides is equal to the square of the 3rd side. Let's check ,

→ 11²+ 12² = 13²

→ 121 + 144 = 169

→ 265 ≠ 169

Hence the ∆ is not a right angled triangle

Find the surface area of the hexagonal pyramid.

The base area is 166.3 cm2.

Answers

Answer:

The surface area of the hexagonal pyramid is 291.93 cm2

Step-by-step explanation:

The complete question is

Given -

Base area of pyramid = 166.3 cm2

Height of the pyramid = 12 cm

Surface area of hexagonal pyramid is

[tex]A=\frac{1}{3} * 3^{\frac{3}{4}}*\sqrt{A_B*(6h^2+\sqrt{3} A_B)+A_B}[/tex]

Here AB is the base area and h is the height

Substituting the given values we get

[tex]A=\frac{1}{3} * 3^{\frac{3}{4}}*\sqrt{166.3*(6*12^2+\sqrt{3} * 166.3)+166.3}\\A = \frac{1}{3} * 2 * \sqrt{(166.3 *1152.04)+166.3)}\\A = \frac{2}{3} * 437.893\\A = 291.93 }[/tex]

The surface area of the hexagonal pyramid is 291.93 cm2

in circle k secant pec intersects chord bkd at f if ae is congruent to ab the measure of arc ed is 32 and arc bc: arc cd is 2:1 then find the measure of angle p

Answers

Answer:

60°

Step-by-step explanation:

Diameter of circle = BD ; Hence, BD = 180°

Arc BC : CD = 2 : 1

BD = BC + CD = 180

BC = 2/3 * 180 = 120°

CD = 1/3 * 180 = 60°

Since ED = 32°

BE = 180 - 32 = 148°

BA = AE

BE = BA + AE

BA = AE = 148° / 2 = 74°

Arc ABC = BA + BC

Arc ABC = 74° + 120 = 194°

P = (Arc ABC - AE) / 2

P =(194 - 74) / 2

P = 120 / 2

P = 60°

solve this parallelogram angle

Answers

Answer:

103

Step-by-step explanation:

angles formed on the same line of a parallelogram are supplementary angles

( the angle with the measure of 77 degrees and the angle labeled "x" are formed on the same line which means they are supplementary )

supplementary angles add up to equal 180

hence, 77 + x = 180

180 - 77 = 103

Hence, x = 103

Answer:

103°

Step-by-step explanation:

Hint :sum of angles of quadrilateral = 180°Simplify:

77° + x° = 180°

x° = 180° - 77°

x° = 103

For what intervals of x is f(x) increasing

Answers

Answer:

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′(x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′(x) < 0 at each point in an interval I, then the function is said to be decreasing on I.

The triangular face of the given prism has an interior angle with a measure of 55° and an exterior angle with a measure of 95°. What is the measure of the marked interior angle?

Answers

Answer:

40 degrees

Step-by-step explanation:

sum of angles in a triangle = 180 degrees

if the exterior angle measures = 95, the interior angle beside it would measure 180 - 95 = 85

marked interior angle = 180 - (85 + 55) = 40 degrees

Answer:

As ewomazinoade states 40° should be the correct answer.

(2x+1) = 0

(x+5) = 0

(2x+1) = 0: x = -1/2
