Answer:
b = 36
Step-by-step explanation:
Assuming this is a right triangle with hypotenuse = c and legs a and b
Then using Pythagoras' identity.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
a² + b² = c², and substituting values
15² + b² = 39², that is
225 + b² = 1521 ( subtract 225 from both sides )
b² = 1296 ( take the square root of both sides )
b =
= 36
You can break the integral of a sum/difference into the sum/difference of the integrals:

The first integral can be solved using the power rule for integrations:

As for the second, remember the chain of derivation of trigonometric functions:

The integration chain is the same, but it follows the opposite direction: the integral of the cosine function is the sine function. So, you have
Since this is an indefinite integral, we must add the generic costant to the answer:

Answer:
113º
Step-by-step explanation:
(x + 14) + (180 - 83) + x + 90 + x = 540
3x + 201 = 540
3x = 339
x = 113
-5x+y=-3. (1) isolate y 1.First isolate a variable.( I isolated y because it was already isolated)
3x-8y=24. (2). 2.Then substitute that into the other equation
—————. 3. Then solve for X
Sub y=5x-3 into (2). 4. Then substitute X into one of the equations
5. Then solve for Y and ta-da you find the answer.
3x-8(5x-3)=24.
3x-40x+24=24. Hope this helped! :)
3x-40x=24-24
-37x=0
X=0
——————
Sub x=0 into (1)
-5(0)+y=-3
Y=-3
.: (0,-3)
