Answer:
b
Step-by-step explanation:
∠ BAD = 90° and
∠ DAC + ∠ CAB = ∠ BAD, that is
x + 2x - 30 = 90
3x - 30 = 90 ( add 30 to both sides )
3x = 120 ( divide both sides by 3 )
x = 40 → b
Answer:
A. 18 3/4
Step-by-step explanation:
It is convenient to rearrange the sum to make it easier to compute:
7 3/4 + 4 3/4 + 6 1/4 = (7 3/4) +(4 +6) +(3/4 +1/4)
= 7 3/4 + 10 + 1
= 18 3/4
The farmer has 18 3/4 rows of radishes altogether.
x=96
all interior angles equal 180
Subtract exterior andgles by 180 to get interior angles because they are supplementary
180-134=46
180-130=50
Get the third angle inside the triangle
180-50-46=84
subtract by 180 to get x because they are supplementary
180-84=96
Therefore x =96

Answer:
7 %
Step-by-step explanation:
- i do not know if you use this but I use S.I=P×R/100×T
- S.I=840
- P for principal(the money you borrow or lend) =6000
- T for time=2 years.
- R for rate=???
- In order to find out the rate, you need to substitute all these numbers into their respective places.
- 840=6000×r/100×2
- 6000/100=60
- 840=60×r×2
- 840=120r
- r=7%
