Answer/Step-by-step explanation:
✔️Reference angle = 50°
Opposite side length = y
Hypotenuse = 8 cm
Adjacent = x
Thus, applying CAH we can find x as shown below:
Cos 50 = adj/hyp
Cos 50 = x/8
8 × cos 50 = x
x = 5.1 (to 1 decimal point)
Thus, applying SOH, we can find y as shown below:
Sin 50 = opp/hyp
Sin 50 = y/8
8 × Sin 50 = y
y = 6.1 (to 1 decimal point)
Answer:
B
Step-by-step explanation:
Since x is 2 wherever you see x put 2
solve x3 + x7+ 2
=(2)3 + (2)7 + 2
= you do the number outside the bracket multiplied by the number inside the bracket
like this
=(2 × 3) + (2 × 7) + 2
= 6+ 14 + 2
= 22
Answer:
y=x+1
or x=y-1
Step-by-step explanation:
Formula for perimeter of a rectangle: P = 2W + 2L
Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14 (cm)
Combine like terms: 8x + 8 cm (simplest form) This is the perimeter.
Now let x = 4: P(x=4) = 8(4) + 8 cm = 40 cm
