Answer:

Angles of a triangle add up to <u>180 degrees. </u>

<u />

So, if we add up all three of the angles of this triangle, we should have a sum of 180 degrees.

4x-10+x+26+x+14=180

4x-10+2x+40=180

6x+30=180

6x=150

x=25

Let me know if this helps!

Can you help me with 17,18,19,20,21

Answer:

See Below

Step-by-step explanation:

#17. You just have to plot the points, this should be super easy. Go to the left 6 (because it is negative) then up four. This is M. Then go right 5 and up 4 and plot A.

#18. Point T is a reflection of A over the X-axis. This is quite simple as well. All you need to do it make your Y coordinate negative? Why Y? You'll see. You need to essentially "fold" the graph at the X line, so your Y value goes from up top at 4 to below the X axis as we're reflecting over the X line. I hope that makes sense. T should be at 5,-4

#19 This is the same process as 18, Over the X coordinate. Make Y negative and plot it. It should be H= -6,-4

#20 You can get this from the answers from #18 and #19.

#21. The formula is Base*2+Height*2, or Base+Base+Height+Height. You want the distance around. I'll have you figure this out, but if you get comment and I'll check back. How many steps do you go up from T to A? How about over from H to T 9 or (M to A)? Once you find how many units your base and height are, use the formula for perimeter to find the answer. Hope this helps! :)

The amount invested at each rate

Investment at 7% = $25000

Investment at 2% = $11,000

<h3>What is investment?</h3>

Investment definition is an asset acquired or invested in to build wealth and save money from the hard earned income or appreciation.

Given:

Larry Mitchell invested = $36,000 at 7% annual simple interest

the rest at 2% annual simple interest.

Total investment = 36000

let the investment at 7% is x

then, invested at 2% = 36000 - x

Total interest earned = $1,970

Simple interest = principal * rate * time

Investment at 4%:

(x * 0.07) + [(36000 - x) * 0.02] = 1970

0.07x + 720 - 0.02x= 1970

0.05x = 1970-720

0.05x = 1250

x= 25000

Hence,

Investment at 7% = $25000

Investment at 2% = $36,000 - $25000 = $11,000
