Answer:   <em>a = [ 65.8]</em>

Step-by-step explanation:

<em>A = 18°</em>

<em>B = 28°</em>

<em>b = 100</em>

<em>a = [ x ]</em>

\dfrac{100}{sin \: 28^{o} } =\dfrac{x}{sin \: 18^{o} } \\\\\dfrac{100}{0.4694715628} =\dfrac{x}{0.3090169944} \\\\x=\dfrac{0.3090169944 \cdot 100}{0.469715628} \\\\x=65.78810\dots \\x \approx 65.8

The measure of ∠d is 150°. What is the value of m∠b + m∠c +m∠e
Zolol [24]

Answer:

C. 120°

Step-by-step explanation:

m∠d = 150°

m∠ a = 90°

The sum of angles at a point add up to 360°

m∠b + m∠c +m∠e = 360° - (90° + 150°) = 120°

For the equation y - 3 = -2(x + 1) the line has a slope of -2 and<br> contains what point
Westkost [7]
It contains multiple points. If you’re looking specifically for a point plug the number that is on the x axis into the equation then solve for y.

What the answer is and how?
Zolol [24]
So what we know is that 15 is the diameter

However the formula to find the area of a circle is A=\pir²
So to convert the 15 in diameter to a radius you have to do 15÷2,which is equal to 7.5

Now we know that the radius is 7.5.
So what we do now is A=\pi7.5²
Then after we find what 7.5² is we get A=\pi56.25
Then what we do is 3.14×56.25, because pi= 3.14.
So when we do 3.14×56.25, we get 176.625
So the answer is A= 176.6 in²
