X+y=6 is..... 
solve for x=0... y=6 
solve for y=0... x=6 
intersect x-axis at (6,0)... calculate the slop: solve for x=1... 1+y=6... 6-1= 5 y=5
calculate the slope: a= y(x=1)-y(x=0)/1=-1 
x+y=6

Lapatulllka [165]

Answer:

  • A, C, E

Step-by-step explanation:

<u>Options:</u>

A. m∠C + m∠E = m∠A

  • Correct. Exterior angle equals to sum of non-adjacent interior angles.

B.   m∠D + m∠F = m∠B

  • Incorrect. Exterior angles have greater value.

C. m∠B + m∠C + m∠E = 180°

  • Correct. Interior angles of a triangle sum to 180°

D. m∠B + m∠C + m∠D = 180°

  • Incorrect. Angles C and D sum to 180°

E. m∠A + m∠ B = m∠E + m∠F

  • Correct. Both sides of equation refer to straight angle.

F . m∠B + m∠C + m∠ E = m∠A + m∠D + m∠F

  • Incorrect. Some of interior angles is not equal to sum of exterior angles.

What is the area of the actual square window shown in the scale drawing?
larisa86 [58]

The area of the actual square window = 2.25 m².

<h3>Scale Drawing</h3>

Scale drawing relates the actual length of an object to its length on a paper.

Given a scale of 1 in = 2 m, it means 1 in on paper is about 2 m of the actual length of the object.

Thus:

  • Length on scale drawing = 0.75 in
  • Actual length = x

Therefore:

1/2 = 0.75/x

  • Cross multiply

x = 1.5 m

Area of the actual square window = 1.5² = 2.25 m².
