Answer:
The correct answer is option 3.
50.8°
Step-by-step explanation:
Cos ∅ = Adjacent side/Hypotenuse
From the given figure we can see that it is a right angled triangle.
<u>To find the value of x</u>
Cos x = Adjacent side/Hypotenuse
Adjacent side =4.3
Hypotenuse = 6.8
Cos x = 4.3/6.8 = 0.6323
x = cos⁻¹ (0.6323) = 50.77 ≈ 50.8°
Therefore the correct answer is third option.
50.8°
B. {-2/3, 10/3}
|3x-4|=6
3x=10
X=10/3
-3x=2
X=-2/3
Answer:
116 cm²
Step-by-step explanation:
Shaded Area = area of the larger circle - area of the smaller circle
Area of the larger circle = πr²
Where,
r = 6.5 cm
Area = π*6.5² = 42.25π cm²
Area of smaller circle = πr²
Where,
r = 2.3 cm
Area = π*2.3² = 5.29π cm²
✔️Shaded area = 42.25π - 5.29π = 36.96π = 116.113264
Area = 116 cm² (3 S.F)
Answer:
3+y and 12+2y
Step-by-step explanation:
I mean they aren't equivalent because if you do PEMDAS (parenthesis, exponents, multiply, divide, add, subtract) Then, you would do 2 times 6 because parenthesis, that equals 12 so the answer would be
3+y and 12+2y
