Answer:
13°
Step-by-step explanation:
2z + 5° + 5z - 6° = 90° { being complementary angles }
7z = 90° + 1°
7z = 91°
z = 91° / 7
z = 13°
Hope it will help :)

x=12/5
Step-by-step explanation:
Answer: 5
Step-by-step explanation: To find the (GCF) or greatest common factor of 15 and 20, begin by finding all of the factors of 3.
Since 15 ÷ 1 is 15, this means that 1 and 15 are factors.
Since 15 ÷ 3 gives us 5, this means that 3 and 5 are factors.
Also, 15 ÷ 5 and 15 ÷ 15 would be factors, but we don't list repeat factors.
Next, we find all of the factors of 20.
Since 20 ÷ 1 is 20, we know that 20 and 1 are factors.
Since 20 ÷ 2 is 10, we know that 10 and 2 are factors.
Since 20 ÷ 4 is 5, we know that 5 and 4 are factors.
Now we look for the largest factor that is shared by the two lists which is 5.
Therefore, the greatest common factor of 15 and 20 is 5.
Square root of 24 is 4*6
square root of 4 is 2
so the answer is 2*square root 6
Answer:
Step-by-step explanation:
"Best estimate' doesn't happen automaticallly, because you have to define "best" in this context. We could merely round all numbers and work with the results:
For example, starting with the work inside parentheses, we have:
5 5/6 - (1 + 4) = 5 5/6 - 5. We must round 5 5/6 up to 6. Then the "best estimate' is 6 - 5, or just 1.
