Answer:
ADB and ABC are similar
x = 8
Step-by-step explanation:
hypotenuse in ADB = 
since two triangles are similar,
solving for x, x=8
Just around the 15 and 3. So it would be
(15-3)x4+9=57
This is because (15-3)= 12
12x4=48
48+9= 57
C=100.I used the Pythagorean theorem just in case next time you run into this problem.
Multiply the height and base of the triangle, then divide by 2. To find the area of the semi-circle, you must do this formula. 3.14 x Diameter × 1/2
Answer : 96 + 25.12 = 121.12cm
0.10d + 0.25q = 3.55
q = d + 3
0.10d + 0.25(d + 3) = 3.55
0.10d + 0.25d + 0.75 = 3.55
0.10d + 0.25d = 3.55 - 0.75
0.35d = 2.80
d = 2.80/0.35
d = 8.....8 dimes
q = d + 3
q = 8 + 3
q = 11 <=== 11 quarters
