Answer 2

Answer:

x=30

Step-by-step explanation:

2/5x+4=16

First: subtract 4 from both sides, 2/5x=12

Second: multiply by 5 on each side, (it cancels out the fraction) to get 2x=60

Third: divide by 2 on both sides, x=30

Answers

Answer:

x = 41

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Sum the 3 given angles and equate to 180

2x + 13 + x - 4 + x + 7 = 180, that is

4x + 16 = 180 ( subtract 16 from both sides )

4x = 164 ( divide both sides by 4 )

x = 41

Answer:

x=41

Step-by-step explanation:

we know that all the angles need to add up to 180

The angle on top is almost a right angle(90) but is not exactly

playing with the numbers will help

95-13=82/2=41

lets continue with this and see if it works out

41+7=48

41-4=37

48+95+37=180

x =

Answers

Answer:

x = 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

(Linear pair angles)

(10x - 20 + 6x + 8)°= 180°

(16x - 12)°= 180°

16x - 12 = 180

16x = 180 + 12

16x = 192

x = 192/16

x = 12

Answer:

so x would equal 12

Step-by-step explanation:

(10x - 20)° + (6x + 8)°= 180°

so you are going to want to combine like terms which would be

10x and 6x, and 20,8

10x+6x=16x

20-8=12

16x-12=180

now you want to get 12 on the opposite side of the equal side so you add (since it is negative) 12 to each side

which gets rid of the first 12

16x=180+12

now you can add 180+12

and you get 192

so now we want to get x by itself in order to do that you must divide

you are going to divide by 16 an each side and the 16 cancels out the first 16

16x/16=192/16

x=192/16

and 192 divided by 16 is 12

so you answer is

x=12

Hope this made sense :)

Answers

Correct question is;

Which of these expressions is equivalent to log (9^2)?

Answer:

D: 2•log 9

Step-by-step explanation:

From log rules, we know that;

log(a^n) = n•log(a)

Applying that rule to this question, we can simplify log (9^2) as;

log (9^2) = 2•log 9

Looking at the options, the correct one is Option D

Answer:

74.6

Step-by-step explanation:

The area of the given triangle in the image is 74.8m².

What is a triangle?

A triangle is simply a polygon with three vertices with three edges.

A scalene triangle is the triangle with no equal sides and angles.

It area can be calculated using the expression;

A = 1/2 × absinθ

Given the data in question;

Length of side a = 15mLength of side b = 11mLength of side c = 22mAngle C = 115°

To determine the area of the triangle, we substitute our given values into the expression above.

A = 1/2 × absinθ

A = 1/2 × 15m × 11m × sin( 115° )

A = 0.5 × 15m × 11m × 0.9063

A = 74.76975m²

A = 74.8m²

Therefore, the area of the given triangle in the image is 74.8m²

Answers

Answer:

92°

Step-by-step explanation:

∠C=180-140=40

∠A+∠B+∠C=180

40+2X+X+2=180

X=46

∠B=46*2=92°

Answer: 92 degrees

Step-by-step explanation:

The exterior angle measuring 140 is equal to the sum of the two remote interior angles.

(X+2) + (2x) = 140. Combine like terms.

2 + 3x = 140. Subtract 2 from both sides.

3x = 138. Divide both sides by 3.

X = 46

Angle b = 2x. Substitute 46 in for x.

Angle b = 2(46)

Angle b = 92
