3x+11 in a right angle

Mathematics
1 answer:
Anna11 [10]4 years ago

To find the x value...
First of all, we know that all angles in the triangle total up to 180 degrees. 
Also, we know that because it is a right angle, there is a little square that means 90 degrees.
we are given one of the angles as 25 degrees

Let's make an equation to solve for the value x then the angle measure
3x + 11 + 25 + 90 = 180
combine like terms
3x + 126 = 180
subtract 126 from both sides to start isolating the variable x
3x = 54
now we will divide both sides by 3 to isolate the variable x
x = 18

Now we aren't done
plug in the value of x into the angle we have to solve for
3x + 11
3 ( 18) + 11
54 + 11
65
The missing angle measure is 65 degrees

Hope this helps :)

Please solve the following proportion, and I will award brainiest to first correct answer.
Over [174]

Answer:

x=5

Step-by-step explanation:

2 2/7 : (0.6x) :: 4/21 : 0.25

Hence, as it is in a perfect proportion, we may use the proportion method..

We multiply the extreme terms and the moderate(near) ones and equalise them.

Hence,

(2 2/7)×(0.25) = (0.6x × 4/21)

16/7 × 25/100 = 6x/10 × 4/21

16/7× 1/4= 3x/5 × 4/21

(16/7 × 1/4)/(4/21) =3x/5

16/7×1/4×21/4×5/3=x

1/7×21×5/3=x

x=5

The distance from Apple to Blue is about 2 times from the distance from Austin to:
andre [41]
First we need to look at the table to figure out what the distance from Apple to Blue is. The chart says this is 150 miles or 253 km. If we would like to know the distance that when multiplied by two from Austin to somewhere is equal to these values, we would need to divide them by two.

150/2 = 75 miles
253/2 = 126.5 km

Now we look at the chart to see which values from Austin to somewhere are closest to these values. From Austin to Turkey would be the closest at 70 miles and 136 km, so this is the answer.

I hope this helps!
