OLga [1]

Answer: 42.9%

Step-by-step explanation:

Percent error is the difference between the measured and known value, which is divided by the known value, and then multiplied by 100%.

Percent error = (Estimated number- Actual number)/Actual Number × 100.

= (60 - 42)/42 × 100

= 18/42 × 100

= 0.429 × 100

= 42.9%

In exercises 1 and 2, Find the value of x.
Kruka [31]

From the given picture, we can see that 2 sides are congruen, then the given triangle is an isosceles triangle. In this triangle the base angles are congruent, so we can draw the following picture:

Now, since interior angles of any triangle add up to 180 degrees, we have

x+\frac{x}{2}+\frac{x}{2}=180

By combining similar terms, we get

\begin{gathered} \frac{4}{2}x=180 \\ 2x=180 \end{gathered}

Then, x is given as

\begin{gathered} x=\frac{180}{2} \\ x=90 \end{gathered}

Therefore, the answer is x=90 degrees
