Move the options into the explanation to show whether the sum of a rational number and an irrational number is always rational or
irrational.
Let x =
Assume x is a rational number.
V7+
By subtracting from both sides of the equation, we find V7
Because x and are both rational numbers, x Šis
However, V7=x and V7 is
SOX-
must be an Irrational number
همه
Since we know
18
Is
the assumption x is a rational number is false.
Thus, V7+ is
an irrational number
a rational number

answer: a and b

step-by-step explanation:

8y^50

step-by-step explanation:

the barter

solution:

we have to construct

∠m nt ≅ ∠p qr

the steps to draw this construction are

step 1: use a compass to draw an arc from point q which intersects the side pq at point a and the side qr at point b.

step 2: draw a segment nt and use the same width of the compass to draw an arc from point n which intersects the segment nt at a point x.

step 3:

step 4: join points n and y using a straightedge.

step 3:

option (d).maintaining the same width of the compass as ab, draw an arc from point x such that it intersects the arc drawn from n in a point y.

to draw   congruent angles , 1. width of compasses while drawing two angles should be same i.e from point at which angle has to be drawn, 2.the distance between the two points where the compass intersects the two sides should be same while drawing any two congruent angles.
