35

since m and n are the midpoints of ab and ac resistively

then ,bc=2mn=16

since m and l are the midpoints of ba and bc respectively

then, ac =2mn =10

then,nc =1/2 × 10 =5

similary, mb=6

then ,perimeter=nc+mb+mn+bc=5+6+8+16=35

Given ab and cb are tangents of p, and m =10°. What is the measure of abp?
yanalaym [24]

Answer:

Hence, ∠ABP=10°

Step-by-step explanation:

We are given that:

AB and CD are tangents of the circle.

Now we are given that m∠ACP=10°.

Also we are given that AP and CP are radius of the given circle that means length of AP and CP are equal.

Also we know that angle opposite to the equal sides are equal that means:

∠ACP=∠PAC.

Hence , ∠PAC=10°.

Also in a triangle the sum of all the angles is 180°.

i.e. ∠ACP+∠PAC+∠APC=180°

this means that 10+10+∠APC=180°

∠APC=180-20

∠APC=180-20=160°

As AB and CD are tangents to the circles that means:

∠BAP=∠BCP=90°

Also APCB is a quadrilateral and we know that sum of all the angles of a quadrilateral=360°

Hence,

∠BAP+∠BCP+∠APC+∠ABC=360°

⇒ 90+90+160+∠ABC=360

⇒ 180+160+∠ABC=360

⇒ 340+∠ABC=360

⇒ ∠ABC=360-340=20°

also ∠ABP=(1/2)∠ABC

Hence, ∠ABP=(1/2)×20°=10°

Hence, ∠ABP=10°

What is the answer for this in square root form
vredina [299]

Answer:

x =  ± sqrt(-49)

or x =  ± 7i

Step-by-step explanation:

x^2 +49 = 0

Subtract 49 from each side

x^2 +49 -49 = 0-49

x^2 = -49

Take the square root of each side

sqrt(x^2) = ± sqrt(-49)

x =  ± sqrt(-49)

We have to complex numbers to solve

x = ± sqrt(-1) sqrt(49)

sqrt(-1) = i

x =  ±i *7

x =  ± 7i

Is this a zero? or a negative? or a positive or an undefined?
beks73 [17]
Do you mean the slope? if so, the slope is undefined. however, the equation for the line would be written as y=3 since all the y values on that line are equal to three. hope this helped!

Write the equation of a line that passes through the points (-3, 7) and (3, 3).
egoroff_w [7]

Answer:

y = -2/3x + 5

Step-by-step explanation:

(-3, 7) and (3, 3)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(3 - 7) / (3 -(-3))

Simplify the parentheses.

= (3 - 7) / (3 + 3)

Simplify the fraction.

= (-4) / (6)

= -4/6

= -2/3

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2/3x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (3, 3). Plug in the x and y values into the x and y of the standard equation.

3 = -2/3(3) + b

To find b, multiply the slope and the input of x(3)

3 = -2 + b

Now, add 2 to both sides to isolate b.

5 = b

Plug this into your standard equation.

y = -2/3x + 5

This is your equation.

Check this by plugging in the other point you have not checked yet (-3, 7).

y = -2/3x + 5

7= -2/3(-3) + 5

7 = 2 + 5

7 = 7

Your equation is correct.

Hope this helps!

To solve: x + 8 = 40
Scorpion4ik [409]

Well, to solve, you would subtract 8 from both sides, which means x would end up equaling 32.

X=32
