Answer:

  all are 90°

Step-by-step explanation:

Vertical angles are congruent, and linear angles are supplementary, so we have ...

  ∠AOC + ∠COB + ∠BOD = 270°

  180° + ∠BOD = 270°

  ∠BOD = 90°

Since the lines cross at right angles, all of the angles are 90°.

Use the figure to find measures of the numbered angles.
Dafna1 [17]

Answer:

1 = 137

2 = 43

3 = 43

4 = 137

Step-by-step explanation:

for the first line, do (180-137 = 43)

then, 43 would be corresponding angle to 2 - making them equal

2 would be vertically opposite to 3, making them equal

137 and 1 are corresponding- making them equal

4 is vertically opposite to 1 - making them equal

Lina20 [59]

Answer: 95metres for the length and the original cost is 2.105

Step-by-step explanation:

Let the initial length be x,

So, x+5=200/2

x+5=100

x=95

Note since the total price is the same and the original length is 95metres.

Therefore, the original cost per metre is

200/95=2.105

Find the 7th term in the
vlada-n [284]

Answer:

Step-by-step explanation:

Given sequence is -5, -1, -5, -25,..

In any arithmetic series  nth term is given by  a + (n-1)d

where a is the first term

and d is the common difference.

 d = nth term - (n-1)th term

For the given  series

a = -5

lets take nth term as 2nd term and 1st term as (n-1)th term

d = -1-(-5)= -1+5 = 84

n th term = a + (n-1)d

using the formula for nth term

4th term = 5 + (4-1)8 = 29
