Answer: 80
Step-by-step explanation:
Sin x = cos (90-x)
Like sin 30 = cos (90-30) =cos 60
So
90-x=90-80
Then
X=80
Verify your solution by finding the sum of the angles of sin and cos, it will be 90
1). 3(x+1)
3x + 3
2) 5(x+8)
5x + 40
3) 4(x+6)
4x + 24
<span>There are 100 possible pairs of numbers.
Half of them start with an even number so only 50 have a first odd number.
Of those remaining 50, half of those have an odd second number.
Leaving 25 of the original 100 to have two odd numbers.
P= 25/100=1/4</span>
With out any functions to choose from...this is difficult. But look for the equation that has a a decimal raised to a power (.07)^2
Answer:
The third angle is 58
Step-by-step explanation:
The three angles in a triangle add to 180 degrees. Let third angle be x
40 + 82+ x = 180
Combine like terms
122 +x =180
Subtract 122 from each side
122-122 +x = 180-122
x = 58
