subtract 103 degrees from 180 to get 77, then add 77 and 37 together and subtract by 180

First you have to subtract 180 to 103 and you get 77 because a straight line always add up to 180, then you have to add that 77 to the 37 that is inside of the triangle and you get 114 and then you subtract 180 to 114 and you get 66 because the sum of the angles inside of the triangle is 180 degrees
The final answer is x= 66
Hope that helps.

Separate 185 into two parts so that one part is 31 more than the other part. Find each part.

Answers

9514 1404 393

Answer:

108, 77

Step-by-step explanation:

Let x represent the larger part. Then ...

x + (x -31) = 185

2x = 216

x = 108

x -31 = 77

The two parts are 108 and 77.

At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?

Answers

Answer:

52 young calves

Step-by-step explanation:

At a dairy farm the ratio of adult milking cows to young calves was 9:2. If there were 234 adult milking cows at the farm, how many young calves were there?

The ration is given as:

adult milking cows to young calves

= 9 : 2

= 234 : x

= 9/2 = 234/x

x = Number of young calves

Cross Multiply

9 × x = 2 × 234

= x = 2 × 234/9

x = 468/9

x = 52

Hence, the number of young calves on the farm is 52.

Find the total surface area of the
following square pyramid:
9 cm
10 cm
SA = [?]cm2

Answers

Answer:

280 cm2

Step-by-step explanation:

1)find the area of square

A=LW

=10×10

=100

2) find the area of triangle

A=B×H÷2

=10×9/2

=45

Coz,there are 4 triangle we multiple by 4

=45×4

=180

3)find the total surface area by adding the two

=100+180

=280cm2

Answer:

SA = [280] cm 2

Step-by-step explanation:

For Lateral Area the formula is 4(1/2 10 x 9)

But the 1/2 makes it 4(1/2 5 x 9)

Then you multiply 5 x 9 = 45 then multiply 45 by the 4 and get 180

Then for Surface Area you put in (180 + 100) = 280

You get the 100 by multiplying 2 of the base numbers together.

(x, y) → (x, -y), x-coordinate stays as is and y-coordinate changes its sign to opposite

Given points:

A(-3, -2) and B(-1, -2)

The image of AB will have coordinates:

A'(-3, 2) and B'(-1, 2)
