Answer:
Option (2). x = 20°
Step-by-step explanation:
In the figure attached,
ΔABC is an equilateral triangle.
By the property of equilateral triangle, all sides of the triangle are equal and measure of all angles of the triangle is 60°.
By this property,
m∠B = 60°
and y = 46 - 16 = 30
By applying Sine rule in ΔBCD,


sin(∠CBD) = 
= 0.6423
m∠CBD = 39.96
≈ 40°
m∠ABD = 60° - 40°
= 20°
Therefore, Option (2). 20° will be the answer.

Given
x-y= -5
x-y=1³
Substitute value of x - y as 1³ in first equation,
=> x-y= -5
=> 1³ = -5
As we can't do anything more to solve, we can finally write as :

Answer:
2, 6, 10, 14
Step-by-step explanation:
For the first term, T1
n = 1
4n - 2 = 4 * 1 - 2
= 4 - 2
= 2
Second term, T2
n = 2
4*2 - 2
= 8 - 2
= 6
Third term T3
n = 3
4*3 - 2
12 - 2
= 10
Forth term T4
n = 4
4*4 - 2
= 16 - 2
= 14
Hence, the first four terms are 2, 6, 10, 14

Answer: B) 1 & 3</h3>
Explanation:
Vertical angles form when we have an X shape like this. They are opposite one another and always congruent. Angles 2 and 4 is the other set of vertical angles.
