Question

tate whether the following are true or false 6X1=6

1) The equation representing the statement “15 less than three times a

number gives 3 is 15-3x=3

2) If two angles in the same plane have common vertex and common side,

then those are called adjacent angles

3) The sum of three angles of a triangle is 3600

4) A closed figure formed by joining three non- collinear points is called a

triangle

5) Perimeter of a rectangle is given by l X b

6) Area of a circle is given by 2​

Answer 1

Step-by-step explanation:

1. the representing the statement 15 less than

number gives 3is 15-3x=3

15-3x=3

=15-3=3x

=12=3x

x=12/3 =x=4

it is false

2.Adjacent Angles are two angles that share a common vertex, a common side, and no common interior points. (They share a vertex and side, but do not overlap.) ∠1 and ∠2 are adjacent angles.

it is a true

3.the sum of angle is a 180

it is false

4.true

5.True

6.true
