Answer:
A=672 m²
Step-by-step explanation:
a²+b²=c² (to find h)
14²+b²=50²
196+b²=2,500
b²=2,304
√b²=√2,304
b=48
h=48
(base×height)÷2
(28×48)÷2
1,344÷2
A=672 m²
C= Colorado B= Boston
C + B = 464
C = 1.2B
Substitute the known value of C from the second equation into the first
C + B = 464
(1.2B) + B = 464
2.2B = 464
Divide each side by 2.2
B = 210.9, rounded to 211 (it's asking for days, not partial days, so round)
If Boston has 211 days of sunshine , then Colorado Springs has 1.2 times that amount. 211 * 1.2 = 253.2 (rounded to 253)
Verification
211 + 253 = 464
Answer:
< A = 148°
Step-by-step explanation:
<A = <B → 6x - 2° = 4x + 48° → 2x = 50° → x = 25°
<A = 6(25°) - 2° = 150° - 2° = 148°
Answer:3.0059 , 3.601 , 3.06
Step-by-step explanation:
the number with less digits behind the decimal has less value
