Step-by-step explanation:
Answer: (06) - (d)
(07) - (d)
(08) - (a)
(09) - 83°
Step-by-step explanation:
According to maths theory, vertically opposite angles are equal.
When two lines intersect each other, the angles opposite to each other are equal.
Ex: According to your figure
Angle a = b and Angle c = d
They are vertically opposite angles.
Your answer (a) says: a = b
This is correct.
Answer (b) says: d = C
This is also correct.
Answer (c) says A + d = 180°
This is also correct, because the sum of the angles on a straight line is 180°
Angle a and d are situated on the straight line l.
Answer (d) says: a = d This is not correct, because a and d are not vertically opposite.
So your answer will be (d).
Adjacent angles - angles which are situated next to each other.
Supplementary angles - if we add two adjacent angles and get the answer as 180°, the two angles will be known as supplementary angles.
Complementary angles - if we add two adjacent angles and get the answer as 90°, they are known as complementary angles.
Vertically opposite angles are not adjacent, supplementary or complementary.
They are equal, so we can easily say that the answer is (d) - equal.
(08) 5b + 2a = 180° (sum of the angles
on a straight line is
180°)
Let's substitute a as 40°
5b + (2^40) = 180°
5b + 80° = 180°
Let's take 80° to the other side, when we do so, 80° becomes a minus
value.
5b = 180° - 80°
5b. = 100°
We know the value of 5b, we have to find the value of 1b
So we have to divide by 5.
b. = 100/5
b. = 20°
b = 20°
In your answer, you have the (a) answer as 20°. So your answer will be (a).
Vertically opposite angles are equal, as we know.
When we have the sum of two vertically opposite angles, it's easy to find the value of one angle.
Divide the value by 2,
We do this because when we divide by 2, we get the value of an equal half.
So let's divide,
166/2 = 83°
So we can say That the value of a vertically opposite angle is 83°.
