Answer:
<h2>x = 9</h2>
Step-by-step explanation:
Answer:
B and D
Step-by-step explanation:
First method :
All angles of a quadrilateral sums to 360 degrees
A + B + C + D = 360
=> 5x^2 + 36x - 336 = 0
=> x = 6 or x = - 56/5 [It gives negative value of angles]
So, A = 58, B = 109, C = 122, D = 71
Second method :
Sum of opposite angles of a quadrilateral inscribed in a circle is 180 degrees
A + C = 180
=> x = 6
So, A = 58, B = 109, C = 122, D = 71

Answer:
3,000
Step-by-step explanation:
6:5
1.2( divided 6 by 5):1 (Divide 5 by 5)
3600 divided by 1.2
3,000
12mi, you just multiply the 3mi and 4mi, i think♀️
Answer:
cot α = 1/tan α = 1/2.4 = 0.42
Step-by-step explanation:
cot α=0.42
sin α = 0.92
we know that cot α = 1/tan α
thus,
cot α = 1/tan α = 1/2.4 = 0.42
we know that
sin(x)=tan(x)1+tan2(x)√
sin α = 0.92
