The formula to find the area of a triangle is A=1/2*b*h

We can plug in what we know to solve for b

33=1/2*b*11 (divide both sides by 11)
3=1/2*b (multiply both sides by 2)
base = 6

Hope this helps

The diagram shows statements to prove that both triangles are congruent.

Hence;

$\begin{gathered} (2) \\ \angle ABC\cong\angle BCD \\ \angle ACB\cong\angle DBC \\ Alternate\text{ interior angles are congruent } \end{gathered}$ $\begin{gathered} (3) \\ BC\cong BC \\ \operatorname{Re}flexive\text{ property} \end{gathered}$ $\begin{gathered} (4) \\ \Delta ACB\cong\Delta DBC \\ \text{Side}-\text{Angle}-\text{Side} \end{gathered}$

Step 1 showed two sides that are congruent for both triangles

Step 2 showed two angles that are congruent

Step 3 showed two sides that are congruent

Therefore, the triangles are congruent by the side-angle-side theorem

Answer: $c = 1.2$

Step-by-step explanation:

First, it is needed to determined the values for x = 1 and x = 2:

$f(1) = -1, f(2)=4$

The sign change within the interval is the most sound evidence of the root existence. According to the Intermediate Value Theorem, there is a number $c$ such that $f(c) = 0$ . Another finding is that $c$ is closer to 1 than to 2.

$c = a + \frac{b-a}{f(b)-f(a)}\cdot[f(c)-f(a)]$

$c = 1 + \frac{2-1}{4-(-1)}\cdot[0-(-1)] \\c = 1.2$

Kevin went fishing and is using a scatterplot to analyze the relationship between the weight of each of the fish he caught in po

Wittaler [7]

Answer:

The answer is A.The points on the scatter plot will go up from left to right because as the weight in pounds increases, the weight in kilograms increases, because when the pounds (lbs.) increases, the kilograms (kg.) increase.
