Answer: A is the correct one. Hope this helps, please consider making me Brainliest.

Step-by-step explanation:

You have to combine both equations and set it equal to 90:

3x + 2x - 5 (I rearranged so like terms are near each other) =

5x - 5 = 90

5x = 95 (Subtraction property)

x = 95/5 (Division property)

x = 19 (Simplify)

90 - 19 = 71 (Solve for the other angle)

The angles are 71 and 19.

Hope this helps, please consider making me Brainliest.

Find the solution of the differential equation that satisfies the given initial condition. y' tan x = 3a + y, y(π/3) = 3a, 0 &lt

Paladinen [302]

Answer:

$y(x)=4a\sqrt{3}* sin(x)-3a$

Step-by-step explanation:

We have a separable equation, first let's rewrite the equation as:

$\frac{dy(x)}{dx} =\frac{3a+y}{tan(x)}$

But:

$\frac{1}{tan(x)} =cot(x)$

So:

$\frac{dy(x)}{dx} =cot(x)*(3a+y)$

Multiplying both sides by dx and dividing both sides by 3a+y:

$\frac{dy}{3a+y} =cot(x)dx$

Integrating both sides:

$\int\ \frac{dy}{3a+y} =\int\cot(x) \, dx$

Evaluating the integrals:

$log(3a+y)=log(sin(x))+C_1$

Where C1 is an arbitrary constant.

Solving for y:

$y(x)=-3a+e^{C_1} sin(x)$

$e^{C_1} =constant$

So:

$y(x)=C_1*sin(x)-3a$

Finally, let's evaluate the initial condition in order to find C1:

$y(\frac{\pi}{3} )=3a=C_1*sin(\frac{\pi}{3})-3a\\ 3a=C_1*\frac{\sqrt{3} }{2} -3a$

Solving for C1:

$C_1=4a\sqrt{3}$

Therefore:

$y(x)=4a\sqrt{3}* sin(x)-3a$

Sum of triangle angles = 180

smallest angle = x

second angle = 3x

third angle = x +35

180 = x + 3x + x + 35

145 = 5x

x = 29 is the smallest

the second is 87

the third is 64

Question in the picture below

jekas [21]

Answer:

htp(

Step-by-step explanation:

Part A If the polygon is above the line, the rotation angle is 180+a.

If the polygon is below the line, the rotation is a.

Part B Rotations may be clockwise or counterclockwise. When working in the coordinate plane: assume the center of rotation to be the origin unless told otherwise. assume a positive angle of rotation turns the figure counterclockwise, and a negative angle turns the figure
