Answer:
-8.8
Step-by-step explanation:
We begin by simplifying the parenthesis through multiplication. Parenthesis is a structure which signals multiplication happening.
We now begin combining like terms across the equal sign by performing the inverse or doing the opposite. Move first the 8.11 by subtracting it from both sides.
Now, move 4.3v across by subtracting it from both sides.
Finally, we divide both sides by the coefficient of v.
Given that ABCD is a parallelogram, the sum of its interior angles is:
360°
A parallelogram is a rectilinear two-dimensional figure with four sides whose opposite sides are parallel. See the image attached.
<h3>What is the sum of the exterior angles of CHFE?</h3>The sum of the exterior angles of any Triangle or any polygon is 360°. Hence, the sum of the exterior angles of CHFE (a polygon) is 360°.
<h3>Which sides are parallel to CE?</h3>The sides that are parallel to CE are:
FH
AD and
<h3>IJ.Which side is perpendicular to CE?</h3>
The side that are perpendicular to CE is side side HH, hence we can state that:
CE ⊥ EH, because both lines intersect each other at right angles.
Because the sum of angles in a triangle is 180° and we already have ∠CEH to be equal to ∠90° hence,
∠C + ∠H? = 180° - 90°
= 90°
<h3>What is the measure of the exterior angles of a Regular Pentagon?</h3>The measure of the exterior angles of a regular pentagon is 72°
