Yes, this identity is true. Those two operations are equivalent.
Answer:
x = 13 and y = 13√3
Step-by-step explanation:
Recall that sin Ф = opposite side / hypotenuse, and that
cos Ф = adjacent sice / hypotenuse.
if we recognize that the angle Ф is 30° here, then we know that:
x = opposite side = hypotenuse * sin 30° = 26*(1/2) = 13.
and....
y = adjacent side = hypotenuse*cos 30° = 26*√3/2 = 13√3
In summary, x = 13 and y = 13√3
Answer: I’m wasnt sure if u r supposed to round up. I assumed that we round down at the hundredth decimal cuz money. Also, make sure to include money signs when you write the numbers down.

Step-by-step explanation:
A. 30 x 1.419= 42.57
B. 45 x 1.13250= 50.9625
C. 56/ 1.13250= 49.44812362
D. 478.90 x 132.87= 63631.443
E. 89.54 x 1.419= 127.05726
F. 5400/ 1.417= 3805.49682875
g. 500/ 132.87= 3.76307669
H. 4500/ 1.67435= 2687.61011735
i. 5689.50 x 1.67435= 9526.214325
J. 458904/ 132.87= 3453.78189207
Answer:
Step-by-step explanation:
Corresponding parts of congruent triangles are equal.
VT = SR
8x- 17 = 15 {Add 17 to both sides}
8x = 15 + 17
8x = 32 {divide both sides by 8}
x = 32/8
x = 4
Corresponding parts of congruent triangles are equal.
∠V = ∠S = 60°
∠W = ∠U = 90°
∠T = ∠R = 2y + 20
In Δ VUT,
∠V + ∠U + ∠T = 180 {Angle sum property of triangle}
60 + 90 + 2y + 20 = 180
2y + 170 = 180
2y = 180- 170
2y = 10
y = 10/2
y = 5
Answer:
x=2
Step-by-step explanation:
5 divided by 2.5 (or 2 1/2)
5/2.5=2
