What is the complement of 86.4 degrees ?

Answers

Answer 1

Answer:

Complement for angles means that the total degrees adds up to 90. (these are called complementary angles, supplementary angles add up to 180 degrees!)

Since you already have 86.4, you simple subtract.

90-86.4=3.6

your final answer is 3.6 degrees.

Divide 132kg in a ratio of 3:3:5

Answers

3 + 3 + 5 = 11 (11 total parts of the ratio.)

132 ÷ 11 = 12 (one part of the ratio)

Multiply 12 by the number of parts in the ratio:

12 × 3 = 36
12 × 3 = 36
12 × 5 = 60

Therefore, the final answer is 36:36:60 kg.

Let the common multiple be x

So, according to the ratio, we will have parts as

3x
3x
5x

Here, they add up to 132

Writing equation.
132 = 3x + 3x + 5x
132 = 11x
x = 12

Now, putting the values !!

3x = 3 × 12 = 36 kg
3x = 3 × 12 = 36 kg
5x = 5 × 12 = 60 kg

M(5,7) is the midpoint of RS the coordinates of S are (6,9) what are the coordinates of R

Answers

Answer:

(4,5) i believe

Answer:

(4, 5)

Step-by-step explanation:

Using the midpoint formula and equating x to 5 and y to 7, that is the coordinates of the midpoint M

let the coordinates of R be (x, y), then

0.5(x + 6) = 5 ( multiply both sides by 2 )

x + 6 = 10 ( subtract 6 from both sides )

x = 4

Similarly

0.5(y + 9) = 7 ( multiply both sides by 2 )

y + 9 = 14 ( subtract 9 from both sides )

y = 5

Thus coordinates of R = (4, 5 )
