Answer:

x+y =90

x-y=42

2x=132

x=66

y=24

Answer:

24° and 66°

Step-by-step explanation:

Complementary angles sum to 90°

let the larger angle be x then the smaller angle is x - 42 and their sum is

x + x - 42 = 90, that is

2x - 42 = 90 ( add 42 to both sides )

2x = 132 ( divide both sides by 2 )

x = 66 and x - 42 = 66 - 42 = 24

The smaller angle is 24° and the larger angle is 66°

Can somebody help me please is it A,B,C,D
kvasek [131]

Answer:

80 degrees

Step-by-step explanation:

The only given angle here is angle 4, which measures 100 degrees.

<u>1) Identify angle relationships</u>

Angle 4 and angle 6 are interior angles, meaning they have a sum of 180 degrees.

<u>2) Solve for angle 6</u>

180-Angle 4=Angle 6

180-100=Angle 6

80=Angle 6

Therefore, the measure of angle 6 is 80 degrees.

I hope this helps!

What is the measure of angle ACB in this triangle
Mrrafil [7]
So, angles A and B added together is 130° which makes the whole angle = 180°-130°=50°

The answer is 180° because it is a supplementary angle and all supplementary angles equal 180° so, all the angles added makes 180°

If dy/dx = x(y-1), find the equation of the tangent line at x=-2 with f(-2)=3
Lapatulllka [165]

Answer:

The equation of the tangent line passing through the point (-2,3) is

 4 x + y +5 =0

Step-by-step explanation:

<u><em>Step(i):-</em></u>

<em>Given that the slope of the tangent</em>

<em>              </em>m = \frac{dy}{dx} = x(y-1)<em></em>

<em>              m = -2( 3-1) = -4</em>

<em>Given point x = -2</em>

<em>          y = f(-2) =3</em>

<em>∴The given point ( x₁ , y₁) = ( -2 ,3)</em>

<u><em>Step(ii):-</em></u>

The equation of the tangent line passing through the point (-2,3)

y - y_{1} = m(x-x_{1} )

y -3 = -4(x-(-2))

y -3 = -4( x+2)

y-3 = -4x -8

4x + y -3+8=0

4x +y +5=0

<u><em>Step(iii):-</em></u>

<em>The equation of the tangent line passing through the point (-2,3) is</em>

<em>   4 x + y +5 =0</em>

<em></em>

--110 = -2(8x + 7)<br> A) {6} B) (16)<br> C) (9) D) (14)
tamaranim1 [39]

Answer:

A) 6

Step-by-step explanation:

-110= -2(8x+7)

Divide both sides by -2

55 = 8x+7

Subtract both sides by 7

48 = 8x

Divide both sides by 8

6 = x
