rectangle?
Mathematics

Answer:

6

Step-by-step explanation:

put unknown as y

area of rectangle = width × long

y(y - 2)=48

y² -2y =48

u can use scientific calculator to find this

y²-2y-48=0

(y-8)(y+6)=0

y=8 y=-6

take the positive value and ignore the negative value

width=y-2 long=8

8-2=6

I hope this help you :)

Please help me with this geometry question, Im pretty sure you need to use SAS congruence rule
Ierofanga [76]

<em>Congruent triangles</em> are two or more triangles with the same length of <u>sides</u> and measure of internal <u>angles</u>. Thus the <em>required</em> proof is as shown below:

From the given diagram, it can be <u>observed</u> that:

AB = AC (<em>similar</em> property of two lines)

AC = AE (<u>similar </u>property of two lines)

Also,

m<A is a <u>common</u> angle to ΔABC and ΔADE

So that it can be <em>concluded </em>that;

ΔABC ≅ ΔADE (Side-Angle-Side property)

Thus since ΔABC ≅ ΔADE are <u>congruent</u>, then;

BC = DE (<u>corresponding</u> sides of <em>congruent</em> triangles)

Triangle ABC has the angle measures shown.
larisa [96]

Answer:

m∠A = 20°

Step-by-step explanation:

Triangle ABC has the following angle measures:

  • m∠A = 2x°
  • m∠B = 5x°
  • m∠C = 11x°

We know that the addition of the angles of a triangle makes 180°, therefore:

m∠A + m∠B + m∠C = 180°

Replacing with data and solving for x:

2x + 5x + 11x = 180

18x = 180

x = 180/18

x = 10°

Which makes the angles:

m∠A = 2*10 = 20°

m∠B = 5*10 = 50°

m∠C = 11*10 = 110°
