Answer:

<h2>C</h2>

Step-by-step explanation:

using the pythagorian theorem, we know that a^2+b^2=c^2. inputting the numbers into this equation, we get

8^2+23^2=c^2

then, using our big math brains, we get 64+529=c^2

adding together the numbers, we end up with 593

just take the sqyare root of that and bada bing bada boom! you get 24.35, or 24.4, therefore the answer is C

Find the area of the triangle belowunits given are cm, cm^2, cm^3

zloy xaker [14]

Answer:

$A_T=150cm^2$

Explanation: We need to find the area of the triangle, We know that the area of any right triangle is:

$A_T=\frac{1}{2}(b\times h)$

Therefore in the information given we have the following:

$\begin{gathered} h=20\operatorname{cm} \\ b=15\operatorname{cm} \end{gathered}$

Therefore the Area of this triangle is as follows:

$\begin{gathered} A_T=\frac{1}{2}(b\times h) \\ \therefore\rightarrow \\ A_T=\frac{1}{2}(20cm\times15cm)=\frac{1}{2}(20\times15)cm^2 \\ A_T=\frac{1}{2}(300)cm^2=150cm^2 \\ \therefore\rightarrow \\ A_T=150cm^2 \end{gathered}$

Note! Units are centimeter-squared
