Answer:360
Step-by-step explanation:70+70+70=120 plus 80+80+80=240
Answer:
It requires of two equations
Step-by-step explanation:
example:
2x +7y = 12
I guess it’s A not sure tho
Answer: x=6
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
Step-by-step explanation:
We know that on both 10 & 12 the angles add up to equal 90° so...
10. 8x+7x=90
15x=90
x=6
12. it's the same in pic as 10
The two angles shown in each are complementary because they add up to 90°.
10 & 12 would be supplementary to one another because they would add up to 180°.
You multiply 4x4=16 and 8x16=128. The volume is 128.
