First lets solve for x we know 3x=90. In this case x=30. Now we can solve for y. We know the triangle needs to equal 180 so y+2(30)=180. So we get y=120. Hope it helps
Answer:
b =21
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
20^2 + b^2 = 29^1
400 + b^2 =841
Subtract 400 from each side
b^2 = 441
Take the square root of each side
sqrt(b^2) = sqrt(441)
b =21
Answer:
1. 4 is the constant
2. x > -2
3. 2.86 inches
^The formula for the circumference of a circle is C=2∏r, in which r=radius. To find the radius, then, we insert 18 in for the circumference. So 18=2∏r. Solving for r gives 9/∏, or approximately 2.86 inches.

<u><em>Answer:</em></u>18
<u><em>Explanation:</em></u>To round a number to the nearest whole number, we would check the fraction part:
If the fraction is <u>less than</u> 0.5, then we would simply ignore the fraction
If the fraction is <u>equal to or more than </u>0.5, then we would add 1 to the whole number and eliminate the fraction.
<u>In the given , we have:</u></span>

<span>.
The fraction part is </span>

<span> which is greater than 0.5
This means that we would add one to the whole number (round it up) and eliminate the fraction.
Therefore, the answer would be 18.
