Answer:
b = 12
Step-by-step explanation:
Complementary angles add to 90 degrees
a+b = 90
78+b = 90
Subtract 78 from each side
78-78+b = 90-78
b = 12
Answer:
The correct answer would be 7. Explaination below
Step-by-step explanation:
8 + 7 = 15
15 + 3 = 18
18 - 11 = 7
Answer:Isolate the variable by dividing each side by factors that don't contain the variable.
w
=-3u/2+2
Twice a increased by the cube of a equals b :
2a + a^3 = b
Multiply 20 and 12 then divide hope this helps :)
