What is the value of x that makes PQ←→||RS←→?

Inessa05 [86]

Answer:

x = 55

Step-by-step explanation:

For PQ and RS to be parallel then

∠ACQ = ∠RDB ( Alternate exterior angles ), thus

3x - 65 = 2x - 10 ( subtract 2x from both sides )

x - 65 = - 10 ( add 65 to both sides )

x = 55

PLEASE HELP IM SERIOUSLY STUCK E

Answer: 2.12 × $10^{-3}$

The coefficient (in green) will be 2.12

Step-by-step explanation:

Scientific notation is written by multiplying the number by a power of 10. This number is a number between 1 and 10.

Since this is a smaller number, we will be multiplying it by a power of 10 to a negative number.

To get this value to a number between 1 and 10, we must multiply it by 10 3 times (also shown as 10³) which gives us 2.12.

To get back to the original value, we multiply this by $10^{-3}$ . This gives us our answer.
