Answer:
57°
Step-by-step explanation:
The sum of both angles is 90°
3x+5x+2=90
8x+2=90
8x=88
x=11
Plug x into the equation
Larger Angle
5(11)+2=57
Smaller Angle
3(11)=33
Like a first step bc. there is a denominator this will be more usefully eliminate it so what you can make it multiplied both sides by 2
- so will get
-2/2x +2*3/2 = 2(-4x+7)/2
(-2x +6)/2 = 2(-4x+7)/2 common denominator the 2 so make the numerators equal and solve for x
-2x+6=-8x+14
6x=8
hope helped
28 in^2
Divide shape into one rectangle and two squares:
Area of rectangle:
10 x 2 = 20 in^2
Area of one square:
2 x 2 = 4 in^2
Multiply that by 2 because we have 2 squares similar in size:
4 in^2 x 2 = 8 in^2
Add the area of the rectangle and two squares:
20 in^2 + 8 in^2 = 28 in^2
Have a nice day
Hope this helps!
If you plot the points you will find you have to use the distance formula. Pick out 2 pairs label them (x1,y1) (x2,y2) then plug it into the distance formula. The repeat for the other sides. So you should get (2,5) (4,3) plug into distance formula what is get it distance between those two points, then (4,3) (-2,-1) plug into distance formula to get an answer, lastly (-2,-1) (2,5) plug in. Now you have three answers add all together and here is your perimeter of a triangle.
