Answer:
The answer is a
Step-by-step explanation:
Answer: Angle 1 = 27
Angle 1 = 63
Remember: complementary angles always add up to 90 degrees.
Set up your equation.
3x + 7x = 90 Combine like terms
10x = 90 Divide by 10 to both sides
x = 9 Answer!
Substitute in (9) for x to find the measurements of the two angles.
Angle 1: 3x
3(9)
27
Angle 2: 7x
7(9)
63
You can also check your work.
27 + 63 = 90
Answer:
b) 7.89*10^4
c) 3.15*10^3
Step-by-step explanation:
2-42)
the coefficient in scientific notation (the number that is not 10^x) has to be greater or equal to 1 and less than 10. so c and b are incorrect.
b) 0.789*10^5
c) 31.5*10^2
b) 0.789*10^5
in order to make 0.789 greater than 1, I would just multiply it by 10. shown below
=0.789*10*10*10*10*10
=7.89*10*10*10*10
=7.89*10^4
c) 31.5*10^2
same concept but this time divide by 10 to make 3.15 which will add another *10 to the exponent
=31.5*10*10
=3.15*10*10*10
=3.15*10^3
