Answer:

Right - 90°

Step-by-step explanation:

Acute angle => less than 90°

Right angle => exactly 90°

Obtuse angle => more than 90° less than 180°
Straight angle =>exactly 180°
Reflex angle => more than 180° , less than 360°
Full angle => exactly 360°

∠ABD = 40°

∠DBC = 50°

∠ABC = 40° + 50° = 90° So, ∠ABC is a Right angle and formed with measure 90°

Hope this helps ^-^

Answer:

ΔABX and ΔEDX

Step-by-step explanation:

Given: AX ≅ EX

BX ≅ DX

SAS implies a congruent relation with respect to Side-Angle-Side between the two required triangle.

AX ≅ EX (given)

BX ≅ DX (given)

<BXA ≅ <DXE (vertical opposite angles)

Therefore,

ΔABX ≅ ΔEDX (Side-Angle-Side, SAS, congruence property)

The sum of two numbers is 51 and the greater number is twice the smaller number. Find the numbers. a) set up the variables Let _

Gelneren [198K]

Answer:

34 and 17

Step-by-step explanation:

a) set up the variables

Let x represent the first number Then y will represent the second number.

b) What is the equation that represents the above situation?

x = 2y
x + y = 51

c) Solve the equation.

Substitute x in the second equation and solve for y:

x + y = 51
2y + y = 51
3y = 51
y = 51/3
y = 17

Then find x

x = 2y = 2*17 = 34

Find the derivative with respect to x of y = (3x + x^2)^5

RSB [31]

<h2>The required "option A) $5(3x + x^2)^{4} (3+2x)$ " is correct.</h2>

Step-by-step explanation:

We have,

$y = (3x + x^2)^5$ ..... (1)

To find, $\dfrac{dy}{dx}$ = ?

Differentiating equation (1) w.r.t. 'x', we get

$\dfrac{dy}{dx}= \dfrac{d[(3x + x^2)^5]}{dx}$

⇒ $\dfrac{dy}{dx}=5(3x + x^2)^{5-1} \dfrac{d(3x + x^2)}{dx}$

[ ∵ $y=x^{n}$ ⇒ $\dfrac{dy}{dx}=nx^{n-1}$ ]

⇒ $\dfrac{dy}{dx}=5(3x + x^2)^{4} (3(1) + 2x^{2-1})$

⇒ $\dfrac{dy}{dx}=5(3x + x^2)^{4} (3+2x)$

Thus, the required "option A) $5(3x + x^2)^{4} (3+2x)$ " is correct.
