Answer:

An isosceles triangle is symmetrical and a right triangle has a 90 degree angle and not symmetrical so they are not the same.

Explanation:

No, an isosceles triangle is not ALWAYS a right triangle. An Isosceles Triangle can be a right triangle, it is a 45–45–90 degree triangle. No, an isoceles triangle is a triangle that has 2 equal sides and angles, and the only condition for a right angled triangle is for it to have a right angle.

Answer:

No

Robin is flying a kite. She ties the 50 foot kite string to the ground. If the kite is

krok68 [10]

$\bold{\huge{\orange{\underline{ Solution }}}}$

<h3>Given :-</h3>

We have given in the question that, Robin is flying a kite.
She ties the 50 foot kite string to the ground .
The kite is flying at 40 feet high

We have to find the measure of the angle the string forms with the group that is angle of elevation.

<h3>Let's Begin :-</h3>

According to the given question,

Hypotenuse AC ( Distance of string from the ground) = 50 ft.
Perpendicular height AB ( Distance of the kite from the ground) = 40 ft.

<h3>Therefore, </h3>

By using trigonometric ratios,

{ $\bold{\pink{ Sin Φ = }}{\bold{\pink{\dfrac{Perpendicular}{Hypotenuse }}}}$

$\bold{\red{ Cos Φ = }}{\bold{\red{\dfrac{Base}{Hypotenuse }}}}$

$\bold{\purple{ Sin Φ = }}{\bold{\purple{\dfrac{Perpendicular}{Base }}}}$ }

The Angle of elevation will be 

[ The angle that is formed between the line of sight and base of the triangle is called angle of elevation ]

$\bold{\pink{Sin Φ = }}{\bold{\pink{\dfrac{AB}{AC }}}}$

$\sf{ Sin Φ = }{\sf{\dfrac{40}{50 }}}$

$\sf{ Sin Φ = }{\sf{\dfrac{4}{5}}}$

$\sf{ Sin Φ = 0.8 }$

$\bold{\green{ Φ = 45.83° }}$

Hence, The measure of the angle the string forms with the ground is 45.83° .

What is the slope y, equals, x, plus, 5?

Blizzard [7]

Answer:

slope = m = 1

Step-by-step explanation:

y = x + 5

slope intercept form is y = mx + b, where m is the slope.

in this case, the m = 1; therefore, the slope is 1

Which statement is true about the extreme value of the given quadratic equation.

RSB [31]

The complete question is

"which statement is true about the extreme value the given quadratic equation? y = -3x^2 + 12x - 33

Oa. The equation has a maximum value with a y coordinate of -27

Ob. The equation has a minimum value with a y coordinate of -21

Oc. the equation has a minimum value with a y coordinate of -27

Od. The equation has a maximum value with a y coordinate of -21"

The quadratic equation has the extreme value at the vertex with a y-coordinate of -21. so, the correct option is D.

<h3>What is a quadratic equation?</h3>

A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.

The given quadratic equation is

y=-3x^2+12x-33

x = -b/2a

For the given equation the vertex :

x = -12/2(-3) = 2

The value of y at x = 2 is:

y = -3(2²) + 12(2) - 33

y = -12 + 24 - 33

y = -21

The extreme is the maximum for the given equation.

The correct choice is D.

WILL GIVE BRAINLEST AS SOON AS I CAN PLZ HELP

9966 [12]

Answer:

x=13.851(repeating 851)

Step-by-step explanation:

The law of sines formula allows to set up a proportion of opposite side/angles ( you're taking the sine of an angle and its opposite side).

When we divide side a by the sine of angle A

it is equal to side b divided by the sine of angle B,

and also equal to side c divided by the sine of angle C

11/27 = x/34

27x = 11*34

27x = 374

x= 13.851.......

11/27 = 0.407......

13.852/34 = 0.407.......
