Answer:
4 inches
Step-by-step explanation:
The radius of a circle is its diameter divided by 2.
8/2 = 4
Ans = 4 inches
U take half of the x term and square it....then add to both sides
14/2 = 7.......7^2 = 49...so u add 49 to both sides
Answer:
I think that the answer is 5a
To find the solutions to this equation, we can apply the quadratic formula. This quadratic formula solves equations of the form ax^2 + bx + c = 0
x = [ -b ± √(b^2 - 4ac) ] / (2a)
x = [ -8 ± √((8)^2 - 4(2)(3)) ] / ( 2(2) )
x = [-8 ± √(64 - (24) ) ] / ( 4 )
x = [-8 ± √(40) ] / ( 4)
x = [-8 ± 2*sqrt(10) ] / ( 4 )
x = -2 ± sqrt(10)/2
The answers are -2 + sqrt(10)/2 and -2 - sqrt(10)/2.
Answer:
Step-by-step explanation:
The exterior angle measure is same as he sum of remote interior angles and the adjacent interior angle make straight angle with the exterior angle
<u>So the adjacent angle is:</u>
<u>The other angles are 2x and 3x as per ratio:</u>
- 2x + 3x = 130
- 5x = 130
- x = 130/5
- x = 26
<u>And</u>
- 2x =2*26 = 52°
- 3x = 2*26 = 78°
<u>So the angles are: </u>
The largest angle is 78°
