The area of a rhombus is 1/2 times the lengths of the diagonals
A = (1/2)(AC)(BD)
Since the diagonals bisect each other, and ed = 8, BD must be 16. Substituting in this for BD and the given area (168) we get the following:
168 = (1/2)(AC)16
168 = 8(AC)
21 = AC
Answer:
3x +45°=180° (due to straight angle)
or, 3x= 180°-45°
or,3x= 135°
or,X=135°/3
X =45°.ans
Step-by-step explanation:

Answer:
<h3>3 : 2 : 4</h3>
<h2>CALCULATIONS</h2>
<h3>Let;</h3>
<h3>Kofi's age = 9</h3>
<h3>kwaku's age = 2/3 *9 = 6 </h3>
<h3>Yaw's age = 2(6) = 12</h3>
<h3>ratio of ages = 9 : 6 : 12</h3>
<h3>Simplest form = 3 : 2 : 4</h3>
Idk this one sorry loooolloooooo
