Answer:

Step-by-step explanation:

∠ABY and ∠ZBU are vertical angles and thus congruent.

Equate the 2 angles and solve for x

3x - 10 = 2x + 40 ( subtract 2x from both sides )

x - 10 = 40 ( add 10 to both sides )

x = 50 → D

Lines P and Q are parallel. What is the measure of angle 1

oksian1 [2.3K]

Answer:

Next time show a picture

Step-by-step explanation:

But! A way you could solve this is to look at the opposite angle of 1 and see what the number is. The number opposite of 1 is always equal to 1. You could also see if there is a number next to 1. The number next to 1 +1= 180 degrees. Good luck!

Answer:

$8.51x10^{-3}cm$

Step-by-step explanation:

In order to add or subtract numbers in scientific notation, the powers of ten must have the same exponent. In this caes the diameter of an average human body cell is a power of -4 and the diameter of a plant cell is a power of -3. In order to add them, we can move the decimal over for the body cell diameter:

$5.1x10^{-4}=0.51x10^{-3}$
