2. Calculate the missing angle: 75 50° a)​

Mathematics
1 answer:
solniwko [45]2 years ago

Answer:

The missing angle is 55°.

Step-by-step explanation:

==========================================

<em>The three interior angles of a triangle add up to 180°. </em>

<em></em>

<u>This means that: </u>

<u></u>x\textdegree + 75\textdegree+50\textdegree=180\textdegree\\\rule{150}{0.5}\\x - \text{unknown angle}

==========================================

Using the equation above, we would solve for x.

x\textdegree + 75\textdegree+50\textdegree=180\textdegree\\\rule{150}{0.5}\\x\textdegree + 75\textdegree+50\textdegree=180\textdegree\\\\x\textdegree + 125\textdegree=180\textdegree\\\\x\textdegree + 125\textdegree-125\textdegree=180\textdegree - 125\textdegree\\\\\boxed{x = 55\textdegree}

The missing angle should be 55°.

==========================================

<em>Hope this helps</em>.

What is the completely factored form of x^4y-4x^2y-5y
AnnZ [28]

Answer:

y(x^2+1)(x^2-5)

Step-by-step explanation:

Factor the expression by first finding a GCF. Each term has the y variable and this can be pulled out as the GCF.

x^4y-4x^2y-5y\\y(x^4-4x^2-5)

To further factor the expression break the polynomial into two binomials.

To factor into two binomials, find factors that multiply to -5 and add to -4.

-5 and 1 are factors and these make the binomials (x^2+1)(x^2-5).

The final factorization is y(x^2+1)(x^2-5)
