Answer:
72/97
Step-by-step explanation:
take angle c as reference angle
to find sin c
sin c = opposite / hypotenuse
sin c = 72 / 97
For this problem, let's first apply the intergral sum rule.
Then, we'll use the reverse power rule on each of these integrals.
So the indefinite integral of is .
Remember that we need our constant of integration, , because of if we take the derivative of a constant, it'll be 0.
Hope this helps!
Answer:
The length of b is 6.7
Step-by-step explanation:
You have way too many unknowns to do much of anything with this. The only way out is to use one of the three geometric means formulas for right triangles. The one that applies here is
and since a + b = 15,
and
Now we look to the right triangle that contains the base b. It has a given angle of 30 degrees, and now we know the side length across from the 30 degrees, we have to think of the trig ratio that relates an angle to the side opposite that angle and to the side adjacent to that angle. That's the tangent ratio. As follows:
and solving for b:
Do this in degree mode in your calculator and you'll get that b = 6.7
Answer:
c and d
Step-by-step explanation:
Since 7y and 5y has the same variable, add them together.
7y + 5y = 12y
We get 12y, so y has to multiply 12 to get 16. I divided 16 by 12, which got me 1.3333333.
16 divide by 12 = 1.33333333
y = 1.33333333 ( 3 keeps going on )
