Answer to written question:
3x + 10x + 7x = 180
Combine like terms
20x = 180
Divide by 20
x = 9
Smallest angle 3x = 3*9 = 27 degrees
Answer to question in picture:
30/6x-2 = 36/5x + 13
Cross multiply
30(5x + 13) = 36(6x-2)
Distribute
150x + 390 = 216x - 72
Subtract 150x
390 = 66x - 72
Add 72
462 = 66x
Divide by 66
x = 7
It will be between the sum and difference of the two given sides.
12 < third side < 42
Answer: 1/5 of the total distance to his grandmothers house was traveled on Sunday
Step-by-step explanation:
The total distance to to his grandmothers house is assumed to be 1
Marks family traveled 7/10 of the distance to his grandmothers house on Saturday. The remaining distance would
1 - 7/10 = 3 /10
They traveled 2/3 of the remaining distance on Sunday. This means that the distance that they travelled on Sunday is
2/3 × 3/10 = 2/10 = 1/5
Answer:158.99
Step-by-step explanation:
The complex number is
-3i
There is no real number
a = 0
b = -3
The value of r is
√(0² + (-3)²) = 3
The trigonometric form of the comoplex number is
y = 3 cos θ
and
x = 0
