60 degrees

This triangle is a right triangle, which means One angle measure of the triangle is 90 degrees. And the given angle is 40 degrees. The total sum of all the angles in a triangle is 180 degrees.

So if you add 40 + 90 + x = 180

You get 130 + x = 180

If you subtract 180 - 130

You get 60.

If I didn’t explain it good enough, let me know so I can explain it better.

If this helped, pls mark branliest.

What is the perimeter of the trapezoid?
andreyandreev [35.5K]

first find the length of the larger base.

Which would be the bottom in this case.


Then, find the sum of all of the sides.

It's important to note that since this is an isosceles trapezoid, both of the non-parallel sides will have the same length.

The length of a rectangle is four more than three times its width. the area of the rectangle is 25. write an algebraic model for
Dafna11 [192]

width (w) = w

Length (L) = 3w + 4

Area (A) = L x w

25 = (3w + 4)w

25 = 3w² + 4w

0 = 3w² + 4w - 25

w = \frac{-2 +/-\sqrt{79} }{3}

w ≈ 2.3, w ≈ -3.6 (width cannot be negative!)

w ≈ 2.3

Length (L) = 3w + 4 = 3(2.3) + 4 = 6.9 + 4 = 10.9

Answer: width=2.3, Length=10.9

A store is having a sale on jelly beans and almonds. For 6 pounds of jelly beans and 2 pounds of almonds, the total cost is $12
CaHeK987 [17]

Solution:

Let each pond of  jelly beans cost $x.

and each pond of almonds cost $y.

Then we can write

6x+2y=12.......(i)

3x+5y=15.....(ii)

Now solve these two equations together using substitution we get

3x=15-5y

30-10y+2y=12\\
\\
-8y=12-30\\
\\
-8y=-18\\
\\
y=2.25\\
\\
3x=15-5y=15-5*2.25=3.75\\
\\
x=1.25

Hence each pond of jelly bean cost 1.25$

Each pond of almond costs 2.25$
