The figure has been re-labelled and attached to this response.
From the figure, the larger right triangle DAB and the small right triangle BCA are similar. This is because;
i. They have two corresponding congruent angles which are<em> the right angle</em>
and <em>angle B</em>
Therefore, we can say that;
<em>Cross multiply</em>
a x a = 13 x 4
a² = 52
a = √52
a = 7.2
Note: The figure showing the similar triangles has also been attached to this response.
Answer:
<em>800÷100 = 8</em>
<em>65×8=520</em>
another way:
<em>100%-65%=35%</em>
<em>35% = 0.35</em>
<em>800×0.35= 280</em>
<em>800-280=</em>520
another way:
<em>65% = 0.65</em>
<em>0.65×800=</em>520
Hope it helped! :)
