Answer:
AFCE = 30
P+Q = 11
Step-by-step explanation:
From the picture, you can see the figure can be decomposed into two identical large triangles with area 20, and 4 identical longer ones, that have to cover the remaining area 40, thus 10 each.
From that you can count the area.
Second puzzle is just trial and error.
Answer:70
Step-by-step explanation:
step 1:add up the angles you know
step 2:subtract the answer (220) from the total angle measure of a square which is 360 then you get 140
step 3: divide 140 by 2 because the two angles on the sides are equivalent and you get 70
Step-by-step explanation:
<h3>• C. P = Cost Price.. , S. P (Sell Price) , </h3>
<h3>→ C.P = 100×S.P/100+Profit (when profit) </h3>
<h3>(a) C.P = 100 × 55/100 + 10 = 5500/110 </h3>
<h2> C.P » $ 50</h2><h3 /><h3 /><h3>(b) C.P = 100 × 558/100+24 = 55800/124 </h3>
<h2> C.P » $ 450</h2><h3 /><h3 /><h3 /><h3 /><h3 /><h3>→ C. P = 100 × S.P/100 - loss (when loss) </h3>
<h3> (c) C. P = 100 × 680 / 100 - 15 = 68000/85</h3>
<h2> C. P » $ 800</h2>
<h3>(d) C. P = 100 × 11.78 / 100 - 5 = 1178/95 </h3>
<h2> C. P » $ 12.4</h2>
(Root symbol) and under that 3x. And then outside of the root symbol -2x
