Our triangle is ABC with ∠C = 90°
1) AB² = BC² + AC² (Pythagorean theorem)
25² = 20² + AC²
AC² = 625 - 400
AC² = 225
AC = 15
2) PΔABC = AB + BC + AC = 25 + 15 + 20 = 60
3) SΔABC = AC * BC * 1/2 = 15 * 20 * 1/2 = 150
Answer: the perimeter is 60 cm and the area is 150 cm² .
Do you need help solving the sequence?
Answer:
<2 = 116 degrees
Step-by-step explanation:
alright so if angle 1 is 64 and you need to find angle 2 you gotta think about whats similar between them. They're both on the same line(railroad) and a straight line is 180 degrees. So now with this info all u gotta do is subtract 180-64 to get 116
Answer:
1500 ft
Step-by-step explanation:
1 yd=3 ft
500 yd*3 ft/yd=1500 ft
The Answer is 76.5, because 153/2 is 76.5
