Step-by-step explanation:
Given

Required
Determine the interval which it belongs
The given number is less than 1
i.e.

And it is greater than 0.

So, the number is located between 0 and 1
i.e.

Answer:
Find length opposite to 30deg
Opposite = tan(30)*42
= 24.2
Whole side = 24.2+10
Find angle of 0 + 30deg: (say x)
Tan(x) = 33.2/42
Arctan(0.79) = x
x = 38.3
The angle to find:
38.3-30:
8.3
The angle is 8.3deg.
34 Degrees because -7 - 27 = -34
Answer:
58.4
119.2
Step-by-step explanation:
Givens
Let one angle = x
Let the other angle = x + 58.4
Together they make 180 degrees.
Equation
x + x + 58.4 = 180 Collect like terms.
Solution
2x + 58.4 = 180 Subtract 58.4 from both sides
2x = 180 - 58.4
2x = 121.6 Divide by 2
x = 60.8
Answer
x = 60.8
x + 58.4 = 119.2
Answer:
12/49
Step-by-step explanation:
First write 2 1/3 as a improper fraction, to do that, first multiply the 2 by the denominator, then add it with the 1, which will result in 7/3
when doing division of fraction you have to remember this, KFG
KFG: Keep Flip Change
you keep the first number or fraction, which is 4/7
then you flip the sign, so you change division in to multiplication
after that, you change or write the reciprocal of the second number or fraction, so 7/3 will be 3/7
Now the equation is
4/7 times 3/7, which is 12/49
