Answer:
∠XDQ : 41°
∠UXD: 139 °
Step-by-step explanation:
Allow me to rewrite your answer for a better understanding and please have a look at the attached photo.
<em>A segment XD is drawn in rectangle QUAD as shown below. </em>
<em>What are the measures of ∠XDQ and ∠UXD ? </em>
My answer:
As we can see in the photo, ∠ADX = 49° and ∠ADU =90°
=> ∠XDQ = ∠ADU - ∠ADX
= 90° - 49° = 41°
In the triangle ADX, we can find out the angle of ∠DXA
= 180° - ∠DAX - ∠ADX
= 180° - 90° - 49°
= 41°
=> <em>∠UXD = </em>180° - ∠DXA (Because UA is a straight line)
=180° - 41°
= 139 °
Hello!
<h2>Answer:</h2>We already know that the formula for area of a rectangle is A = l × w.
Notice how the width and the length are being multiplied to find the area.
Well, to find the width, we must do the <em>opposite</em> of multiplication, which is division.
Since we already have the length, all we have to do is divide the area by the length for each of the questions.
1:
A = l × w
55.5 = 9.25 × w
= 6
2:
A = l × w
48.75 = 7.5 × w
= 6.5
3:
A = l × w
44 = 5 × w
= 8.8
4:
A = l × w
31.25 = 5 × w
= 6.25
