<span>m?ABC = 60° Looking at the diagram, you have triangle ABC. For m?BAC you are given a value of 75°, m?ACB is a supplementary angle to 135° which means it has a value of 180° - 135° = 45°. Finally, ?ABC is the 3rd angle of triangle ABC. Since all the angles in a triangle add up to 180°, you simply need to do the subtraction. 180° - 75° - 45° = 60° Therefore m?ABC = 60°</span>

on the blueprint of the house 44 millimeters represents 8 meters. the length of the living room is 33 millimeters on the bluepri
Scilla [17]
So if 44=8 and 33=x, solve for x. 
The problem would look like this : 44mm = 8m
                                                      33mm =  x
You would cross multiply giving you this : 44x = 264
Then divide 264 by 44 to isolate x, then you should get this : x = 6
6m will be your answer.

When using the power rule, the original coefficient:__________a) Is multiplied by the original exponent.b) Only changes if the f
sleet_krkn [62]

Answer:

a) Is multiplied by the original exponent.

Step-by-step explanation:

the power rule works like this:

you want to find the derivative of ax ⁿ

where n is the exponent and a is the coefficient

the derivative would equal (n ⋅ a)xⁿ⁻¹

e.g. you want to find the derivatives of 5x⁴

f'(x) = (4 ⋅ 5)x⁴⁻¹ = 20x³

f''(x) = (3 ⋅ 20)x³⁻¹ = 60x²

f'''(x) = (2 ⋅ 60)x²⁻¹ = 120x

f''''(x) = (1 ⋅ 120)x¹⁻¹ = 120

A rectangular room is twice as long as it is wide, and it’s perimeter is 60 meters. Find the width
zhannawk [14.2K]

Answer:

20 m

Step-by-step explanation:

The width is half the length, and the perimeter is the sum of the lengths of all sides. We can write the equation of the perimeter as ...

... 60 m = L + L/2 + L + L/2

... 60 m = 3L . . . . . collect terms

... 20 m = L . . . . . . divide by 3

The midpoint of \overline{\text{AB}} AB is M(5, 1)M(5,1). If the coordinates of AA are (3, 6)(3,6), what are the coordinates of
Bingel [31]

Answer:

<em>(7, -4)</em>

Step-by-step explanation:

The formula for calculating midpoint is expressed as;

M(X, Y) = (x2+x1)/2, (y1+y2)/2

X = x1+x2/2

Y = y1+y2/2

Given

X = 5, Y = 1, x1 = 3, y1 = 6

Get x2

X = x1+x2/2

5 = 3+x2/2

10 = 3+x2

x2 = 10-3

x2 = 7

Get y2;

Y = y1+y2/2

1 = 6+y2/2

2 = 6+y2

y2 = 2-6

y2 = -4

<em>Hence the coordinate of B is at (7, -4)</em>
