Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
<u>The missing angles</u>
- Both the unknown angles have the same value as the other two angles in the triangles are the same
- ∠(missing) = 180 - (72 x 2)
- ∠(missing) = 180 - 144
- ∠(missing) = 36°
⇒ The sides are <u>equal</u>
⇒ Angles are <u>not 90°</u>
⇒ It is a <u>rhombus</u>
<u></u>
<u>Question 2</u>
- The <u>diagonals</u> of the shape <u>bisect other</u> (Statement 1)
- NY = NW (given)
- XN = NZ (given)
- ∠XNY = ∠WXZ (vertically opposite angles)
- ΔXNY ≅ ΔWXZ (SAS)
- They form <u>two congruent triangles</u> (Statement 2)
- From these two statements, it is evident the figure is a <u>parallelogram</u>
<h2><u>Answer</u></h2>
11 209/250
<h2><u>Explanation</u></h2>
5.815 + 6.021
First add the numbers the way they are.
5.815
<u> +6.021</u>
<u> 11.836</u>
The whole number is 11.
11.836 = 11 + 0.836
0.836 = 836/1000
Dividing byy 4 we get,
0.836 = 836/1000 = 209/250
∴ 11.836 = 11 209/250

Answer:
Bike=125 Skateboard= 74
Step-by-step explanation:
x + (x-51)= 199
2x-51=199
2x=250
x=125
125+ (125-51)=199
125+74=199
