Answer:
The given measurement will produce only 1 triangle
Step-by-step explanation:
Given:
a = 13
c = 15
∠A = 53°
now, applying the law of sine, we have
(a/sinA) = (c/sinC)
on substituting the values, we get
(13/sin53°) = (15/sinC)
or
sinC = 0.921
or
C = 67.14°
also, sum of all the angles of a triangle = 180°
thus,
∠A + ∠B + ∠C = 180°
53° + 67.14° + ∠B = 180°
or
∠B = 59.85°
now,
again applying the law of sine, we have
(a/sinA) = (b/sinB)
on substituting the values, we have
(13/sin53) = (b/sin59.85°)
or
b = 14.07
now, we have all the dimension of the triangle and have obtained the unique values,
Therefore, the given measurement will produce only 1 triangle
Answer:
part of cake was eaten
Step-by-step explanation:
Given: Vanessa ate 2 slices of cake. ishaan ate 1 slice. there were 1 slice remaining.
To Find: If all the slices were the same size, what fraction of the cake was eaten.
Solution:
Slices of cake eaten by Vanessa =
Slices of cake eaten by Ishan =
Slices remaining =
Total number of Slices =
=
=
Total number of Slices Eaten =
=
=
Fraction of Slice eaten =
=
Therefore the fraction of slice eaten is
16x2y2 + 9z2, a perfect square trinomial
16x2y2 – 24xyz + 9z2, the difference of squares
16x2y2 – 24xyz + 9z2, a perfect square trinomial
The correct option is .
Further explanation:
The binomial algebraic expression is an algebraic expression that consists two terms and it is separated by plus or minus.
Binomial expression can be mathematically expressed as,
The trinomial algebraic expression is an algebraic expression that consists three terms and it is separated by plus or minus.
Trinomial expression can be mathematically expressed as,
Here, are the real numbers.
The square of the binomial can be written as,
Given:
The given algebraic expression is .
Step by step explanation:
Step 1:
The square of the binomial can be written as,
Similarly, the expression can be written as,
Step 2:
The distributive property can be used to solve the square of the binomial.
The distributive property can be expressed as,
Now apply the distributive property to solve the expression .
Therefore, the expression is the perfect square of the binomial .
The expression is the trinomial.
Thus, option D a perfect square trinomial is correct.
