zhannawk [14.2K]3 years ago
3 0

Step-by-step explanation:

Therefore,

(x+20) + (x-10) + (2x-30) = 180° (Sum of interior angles of a triangle)

Or, x+x+2x+20-10-30 = 180°

Or, 4x-20 = 180°

Or, 4x= 180+20

Or, 4x= 200°

Or, x= 200°/4

Therefore, x= 50°

So,

(x+20)

= 50+20

=70°

(x-10)

= 50-10

40°

(2x-30)

= 2×50-30

=100-30

=70°

Hope it helped, If it did, please mark it as the brainliest answer :)

<h2>Answer:</h2>

The number is -2.

<h2>Step-by-step explanation:</h2><h3>Written out, our equation looks like this:</h3><h3>(-5·x)+2=12</h3>

We'll start of by taking our final result of 12 and subtracting 2, as the beginning of the statement says "two more."

<h3>12 minus 2 gives us 10.</h3>

Now, since the statement says "the product of -5," we will take this 10 and divide by -5.

<h3>10 divided by -5 gives us -2.</h3>

This means that our number, x equals -2. Of course, we must input this solution to double check our work.

<h3>(-5·<u>-2</u>)+2=12</h3><h3>10+2=12</h3><h3>12=12</h3>

<h2>Our final answer is x=-2!</h2>

Please help solve for PQ.
DerKrebs [107]
This problem cannot be solved unless we are given figure NPQR is a rhombus.
In that case, then all sides are equal, meaning 
5x+16=9x-32
Solve for x
9x-5x=16+32
4x=48
x=12

Each side (including PQ) then equals 5x+16=5*12+16=76
