Answer:
∠abc=34°
∠dbc= 44°
Step-by-step explanation:
(5x+4)+(5x-6)=78
10x-2=78
10x=78+2
10x=80
x=8
put x in each equation
∠abc= 5x8-6
40-6
34°
78-34= ∠dbc
∠dbc= 44°
Answer:
24
Step-by-step explanation:
1. First, let's find the common ratio between the sides we know.
2. The number 4 is the scale factor, so we multiply 6 by 4 to get the missing side length.
Therefore, the missing side length is 24.
I would believe it to be 22
Answer:
115%
Because to get a percent from a decimal you multiply by 100 so you move the decimal twice to the right
The concept used here is the place values. Each digit of a number holds it own value that is determined by its relative location within the number. Starting on the rightmost digit, the value increases by 10. The ones digit has a value of 1. The tens digit has a value of 10. The hundreds value has a value of 100.
The rightmost 4 has a value of 1, so its exact value is 4*1 = 4. The middle 4 is the tens place, so its exact value is 4*10 = 40. The third 4 from the right is in the hundreds place, so its exact value is 4*100 = 400.
