Ineed not sure how to answer this

D. 123

Step-by-step explanation:

If angle BAC is 57, then so is the one opposite to it, angle BCD. So together, they would make 114 degrees (57 +57).

If there are a total of 360 degrees in a rhombus and 114 are taken up, then that means we have 246 degrees left (360 - 114 = 246).

These 246 degrees are equally shard by angles B and D. Therefore, we just have to divide by 2 to get the

246 / 2 = 123. And that's your answer!

"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).

step-by-step explanation:

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
