Answer 1

Answer:

GIVEN : magnitude of angle B = 68°

magnitude of angle C = 70°

So the value of angle A (interior) be A

We know A + angle B + angle C = 180° [ Sum of all three interior angles of a triangle = 180°]

=> A + 68° + 70° = 180° [By linear equation we can find the value of A]

=> A + 138° = 180°

=> A = (180 - 138)°

=> A = 42°

A(interior) + A(exterior) = 180° [ Sum of all adjacent angle on a straight line =180°]

42° + A(exterior) = 180°

=> A(exterior) = (180-42)°

=> A(exterior) = 138°

As because A(exterior) = x = 138° (ans)

Answer:

(x−3)(x+5) is the factorised form of the expression.

Step-by-step explanation:

x2+2x−15

We can Split the Middle Term of this expression to factorise it.

In this technique, if we have to factorise an expression like ax2+bx+c, we need to think of 2 numbers such that:

N1⋅N2=a⋅c=1⋅(−15)=−15

AND

N1+N2=b=2

After trying out a few numbers we get N1=5 and N2=−3

5⋅(−3)=−15, and 5+(−3)=2

x2+2x−15=x2+5x−3x−15

=x(x+5)−3(x+5)

=(x−3)(x+5) .

(x−3)(x+5) is the factorised form of the expression.

Answer:

(x - 3) and (x + 5) is the factorize form of x² + 2x - 15

Step-by-step explanation:

[tex] {x}^{2} + 2x - 15[/tex]

[tex] {x}^{2} + 5x - 3x - 15[/tex]

[tex]x \times (x + 5) - 3(x + 5)[/tex]

An ice cream shop offers 40 different flavors. To simulate the most commonly chosen flavor, you could write the name of each flavor on a piece of paper and put it in a bag. Draw from the bag 100 times, and see which flavor is chosen the most. Complete the statement about why this simulation is not a good way to figure out the most-commonly chosen flavor.

Drawing from the bag is (random or not random),
but people usually (do or do not). Randomly choose ice cream flavors.
