We have been given that Circle C has diameter AE with a length of 2 cm, and a central angle with the measure . We are asked to find the length of arc DE.
We will use arc length formula to solve our given problem.
, where,
= Arc length,
= Central angle in degrees.
r = radius of circle.
Since AE is diameter, so radius will be half of AE.
Upon rounding to nearest tenth, we will get:
Therefore, the length of arc DE is approximately 0.7 cm.
Smallest angle is °
<u>Step-by-step explanation:</u>
Here we have , Quadrilateral WXYZ has interior angles that meet the following criteria:
Angles W and X are congruent.
According to question , angles are congruent i.e. Both angle measure same
⇒
Now ,
• The smallest angle's measure is 100° less than twice the measure of W.
According to above statement we have ,
Smallest angle =
• The largest angle's measure is 10º more than twice the measure of X. ( correction , in question given as 2X )
According to above statement we have ,
Largest angle =
Now , We know that sum of all 4 angles in 360 i.e.
⇒ { X=W }
⇒
⇒
⇒
Smallest angle is :
Therefore , Smallest angle is ° .
Answer:
x=3
Step-by-step explanation:
2x^2= 18
divide the two by 18 —- x^2=9
now x *x= 9 or the square root of 9

Step-by-step explanation:
Answer:
The value of k is -5.
Step-by-step explanation:
To find the value of k, start by using the known information we have in the equation for slope. The equation is below.
m(slope) = (y2 - y1)/(x2 - x1)
In this equation, the first ordered pair would be (x1, y1) and the second would be (x2 , y2). So we put the values in for these variables and we get.
-1/5 = (-7 - k)/(6 + 4)
-1/5 = (-7 - k)/10
Now we can use cross multiplication to solve for k.
-1/5 = (-7 - k)/10
-1*10 = 5(-7 - k)
-10 = -35 - 5k
25 = -5k
-5 = k
