Answer:
(a) a ≈ 22.7 meters, (b) c ≈ 10.6 meters, (c) ∠A = 65°
Step-by-step explanation:
assuming side a/c is side BC/AB since it's opposite of angle A/C
(a) SOH CAH<em>(cos = </em><em>adjacent side/hypotenuse</em><em>)</em> TOA
=> cos (25°) = BC/AC or a/b
=> cos (25°) = a/25
=> a = cos (25°) × 25
=> a ≈ 22.7
(b) SOH<em>(sin = </em><em>opposite side/hypotenuse</em><em>)</em> CAH TOA
=> sin (25°) = AB/AC or c/b
=> sin (25°) = c/25
=> c = sin (25°) × 25
=> c ≈ 10.6
(c) 180° - 25° - 90°(the right angle) = 65°
Answer:
the third option would be the best
Step-by-step explanation:
2/7 + 3/8 = 37/56 = .660
1/10 + 3/8 = 19/40 = .475
correct answer------------ 1/6 + 1/8 = 7/24 = .291
2/9 + 1/8 = 25/72 = .347
Since the square root of 64 is 8, 8 has an absolute value, so it can be opposites as it, eg. 8 = -8.
What are the x-intercept and y-intercept of the graph of y=−12x+4 ?
Set y=0 to find x-intercept,
y=−12x+4
(0)=-12x+4
0-4=-12x+4-4
-4=-12x
-4/-12=-12/-12x
1/3=x
Set x=0 to find y-intercept
y=−12(0)+4
y=4
