if angle 1 and angle 2 form a linear pair. if m<1=5x+9 and m<2=3x+11, find the measure of both angles
Ulleksa [173]

Answer: m\angle 1=109\°\\m\angle 2=71\°

Step-by-step explanation:

It is important to remember the definition of "Linear pair angles".

By definitiion "Linear pair angles" are two angles which are adjacents and supplementary.

Based on this, we know that the angles \angle1 and \angle2 are supplementary, which means that they add up to 180 degrees.

So, knowing that:

m\angle 1=5x+9\\m\angle 2=3x+11

We can write the following expression and solve for "x":

(5x+9)+(3x+11)=180\\\\8x=180-20\\\\x=\frac{160}{8}\\\\x=20

Therefore, substituting, we get that the measures of the angles \angle1 and \angle2 are:

 m\angle 1=5(20)+9=109\°\\\\\\m\angle 2=3(20)+11=71\°

2.5 hours travelled and 187 distance traveled in miles ( I have to find the unit rate)
Elena L [17]

Answer:

The first one is 75 and the second one is 81

Step-by-step explanation:

put 187.5 into calculator then divide it by the bottom number/denominator in this case 2.5 and then you get 75

put 303.75 into calculator then divide it by the denominator or 3.75 and you get an answer of 81

so 81 miles per hour

I really hope this helps!

In a triangle ABC, if angle B= 60° and the ratio of two sides is a: C= 2: sqrt3 + 1, then angle A=
yawa3891 [41]

Answer:

<em>Well, Your best answer will be is </em><em>45° </em><em>Because, Given two sides and the angle in between,  we can calculate for ∠A using the sine law: </em>

<em> </em>

<em>b / sin B = a / sin A </em>

<em> </em>

<em>2.45 / sin 60 = 2 / sin A </em>

<em> </em>

<em>sin A = 0.707 </em>

<em> </em>

<em>A = 45˚ </em>

<em> </em>

<em>Therefore the answer is letter A: 45 </em><em>Good Luck! </em>

If a city with a population of 50,000 doubles in size every 16 years, what will the population be 32 years from now?
Oksanka [162]
Pretty sure its 200,000 because, 16 goes into 32 twice and its doubles 50,000 every 16 years, so it would be 50,000 multiplied by 4 since it doubles . and that would give you 200,000. (it was hard explaining this)
