Answer:

C. 42° and 48°

Step-by-step explanation:

Complementary angles: Angles that add up to 90°.

So we can set up an equation..

(x + 3) + (x + 9) = 90

2x + 12 = 90

2x = 78

x = 39°

Now we can find the angles.

Angle 1:

(x + 3)

= 39 + 3

= 42°

Angle 2:

(x + 9)

= 39 + 9

= 48°

And we can check to see if they add to 90°,

42° + 48° = 90°

4th term of (4x-y)^9
Neko [114]
Now, let's do the same as we did for the previous one here.

\bf (4x-y)^9\implies 
\begin{array}{llll}
term&coefficient&value\\
-----&-----&-----\\
1&+1&(4x)^9(-y)^0\\
2&+9&(4x)^8(-y)^1\\
3&+36&(4x)^7(-y)^2\\
4&+84&(4x)^6(-y)^3
\end{array}

notice again, how did we get 84 for the 4th element's coefficient? well 36 * 7 / 3.  and so on.  And you can just expand it from there.

Marianna [84]
I can not set up a 2 way table online but what they want is a collom of the information neatly laid out...

With the 9th graders in one collom and the 10th graders in the other

like this

                           9th grader   10th grader
# of students          32                      40
# of participated    32                      18

Draw this out with lines and it will be correct.

I hope this helps GOOD LUCK...this is tough math for a middle schooler.

Will works 7 hours a day, 6 days a week.
exis [7]
A day
= £9.20x7
= £64.40

6 days
£64.40x6= £386.40

The wages he has after he shared it with his mom
£386.40/7x5
= 55.20x5
= £276

£1932/£276= 7

It will take him 7 weeks to afford a car worth £1932.

Classify triangle ABC by its angles if m
mezya [45]
It seems that you missed the essential details for this question, but anyway, I have found the complete question. So given that angles m<A=32 and m<B=55, let us find first for the measure of angle c. So m<C= <span>180 - 32-55 = 93, so it is 93. Based on these measurements, Triangle ABC is an obtuse triangle. By definition, an obtuse triangle is a triangle in which one of its angles is obtuse or which measures more than 90 degrees. Hope this answer helps.</span><span>
