Step-by-step explanation:
-17 < 3 - 5x
-3 -3 step 1: subtract 3 from both sides
-20 < -5x
/-5 /-5 step 2: divide both sides by 5
4 < x
Since 2+8 =10 you would just have 3 left to add so it would be 10+3=13
Answer:
Step-by-step explanation:
ABC have sides: 5, 7 and 10
5^2 + 7^2 = 25+47 = 72 < 10^2
so triangle ABC is obtuse
JKL has sides: 12, 35 and 37
12^2 + 35^2 = 144 + 1225 = 1369 = 37^2
so triangle JKL is right-angled
PQR has sides 12, 10 and 16
12^2 + 10^2 = 144 + 100 = 244 > 16^2
so triangle PQR is acute
The answer to this question is 360ft^2
