4) The triangle on the right is an equilateral <br><br> Find the value of X and Y

ozzi

Answer:

<em>angle Y is 29 degrees</em>

<em>angle X is 120 degrees</em>

Step-by-step explanation:

Well, if the triangle is an equilateral, then all the angles are equal to

60 degrees

that means the the angle at the top point is 60+31 = 91 degrees

the right point is 60 degrees

every triangle has 180 degrees total

180 - (91+60) = 29 degrees

NOW FORGET ABOUT THE EQUILATERAL FOR A BIT

180 = 31+x+29

simplify

180 = 60+x

subtract 60 from both sides

120 = x

If a car with an average speed of 40 miles per hour drives for 45 minutes how far will it have gone

REY [17]

Answer: $30\ miles$

Step-by-step explanation:

The average speed of the car is 40 miles per hour:

$V=40\ \frac{mi}{h}$

The car drives for 45 minutes:

$t=45\ min$

Since 1 hours has 60 minutes, we can convert the time from minutes to hours:

$(45\ min)(\frac{1\ h}{60\ min})=0.75\ h$

Knowing these values, we can use the following formula for calculate the distace "d":

$d=V*t$

Therefore, substituting values into the formula, we get:

$d=(40\ \frac{mi}{h})(0.75\ h)\\\\d=30\ mi$
