Answer:
232cm^2
Step-by-step explanation:
Formula A= 1/2ap
1/2 (8)(58) = 232
I got 65 by 360 /5 sides=72
72/2=36
Tan 36×8= 5.8 ×10 small triangles =58
11. m ∠ BCE = 25 °
m ∠BAD = 39°
12. n = 11. 5°
13. The quadrilaterals are rectangle and parallelogram. Option A and C
14. HK = 8cm
<h3>How to determine the angles</h3>
11. From the figure shown, we have that;
m ∠ EBC = 27°
m ∠ ADE = 52°
To find
m ∠ BCE
Note that m ∠ ADE is alternate and equal to m∠ DEC = 52 and is also on a straight line with ∠BEC
52 + ∠BEC = 180°
∠BEC = 180 - 52° = 128°
Remember that ∠BEC, ∠ BCE and ∠ EBC are angles in a triangle which sum up to 180°
128° + ∠ BCE + 27° = 180°
∠ BCE = 180 ° - 155°
∠ BCE = 25 °
To determine m ∠BAD
65° + 76 + m ∠BAD = 180° , sum of angles in a a triangle
m ∠BAD = 180 - 141
m ∠BAD = 39°
12. Value of n is gotten by equating the two lengths
( 10n + 19) = (12n - 4)
collect like terms
10n - 12n = -4 - 19
- 2n = -23
n = -23/-2
n = 11. 5°
13. The only quadrilaterals with congruent diagonals are;
14. To find line HK
Substract the shortest line, IJ from the longest line GL
HK = GL - IJ
HK = 15 - 7
HK = 8cm

What you can do for this case is to use the following rule of three to solve the problem:
1spoonful ---> 5ml
4spoonful ---> xml
Clearing the value of x we have:
x = (4/1) * (5)
x = 20ml
answer:
Mari adds 20ml of honey in all
The answer is 11 and 12, because if you add them you get 23 and if you subtract them you get 1.
