Step-by-step explanation:
I didn't need the other angles, but right of the bat you can tell it's two right triangles back to back.
<em>y </em> has to be 90° , as you have noticed they already gave you 70° on the right side of the shape meaning if you were to add 90 which is why plus 70 what would that give you? 160.
the total interior for a triangles angles has to be 180°. if you do the math 180 - 160 you get the leftover 20° for x.
I suck at explaining stuff, hope this helps

Answer: 31.5
area of a triangle= bh/2 —> 7 times 3 divided by 2 equals 10.5
area of a rectangle = bh —> 7 times three equals 21
21+10.5=31.5
Answer:
2x(3x-2)
Step-by-step explanation:
3/14 - 1/7
= 3/14 - 2/14
= 1/14
so, 3/14 - 1/7 = 1/14
