1) given: mlhe=84°

find: m∠eyl.

2)given: m∠eyl=72°
find: m arc ehl, m arc lve

Part 1) The measure of angle EYL is

Part 2) The measure of arc EHL is and the measure of arc LVE is

Step-by-step explanation:

we know that

The measurement of the outer angle is the semi-difference of the arcs which comprises

Part 1)

Let

x------> the measure of arc LHE

y----> the measure of arc LVE

we know that

Find the value of y

Find the measure of angle EYL

substitute the values

Part 2)

Let

x------> the measure of arc EHL

y----> the measure of arc LVE

we know that

-----> equation A

substitute

--------> equation B

equate equation A and equation B and solve for y

Find the value of x

therefore

The measure of arc EHL is

The measure of arc LVE is

2.

according to newton’s cannonball model, what happens if the cannonball's velocity is enough to overpower the pull of earth’s gravitystep-by-step explanation:

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
