Sum of angles in a triangle=180

70°+60°+(8x+2)°=180°

130°+(8x+2)°=180°

Collect like terms

(8x+2)°=180°-130°

8x+2)°=50°

8x=50-2

8x=48

x=6°

How can you decompose the composite figure to determine its area
Y_Kistochka [10]
They are usually made up of smaller and simpler figures so break them up into smaller shapes and find the separate areas and then add them all up together to get the whole total for the one. I hope that makes sense.

BRAINLIESTTT ASAP!<br><br> please answer
Pie
When you add the two angles together, they should equal 90 degrees (according to the square marker). So, all you have to do is add the two angles together, make them equal to 90, and solve for x.
2x+8+5x-2=90
7x+6=90
7x=84
x=12

Now, we substitute x and solve for the angles.
2x+8
2(12)+8
32 degrees

5x-2
5(12)-2
58 degrees

To double check our answer, we can add the two angles together and see if we get 90.
32+58=90 yes

Our answer is correct
