First find the value of h, or the height using the pythagorean theorem.

13^2=15^2+h^2
289=225+h^2
h^2=64
h=8

Then use the formula bh/2 to find area of the triangle.

10*8/2=40

Step-by-step explanation:

For this issue the statistical programme performance is:

Two overview hypothesis test sample variance:

$\to \sigma_1^2$ =Population variance 1

$\to \sigma_2^2$ = Population variance 2

$\to \frac{\sigma_1^2}{\sigma_2^2}=$ Two variance ratios

$\to H_0: \frac{\sigma_1^2}{\sigma_1^2}=1\\\\\to H_A: \frac{\sigma_1^2}{\sigma_1^2}\neq 1$

Following are the result of the Hypothesis test: $Ratio \ \ \ \ \ \ \ \ \ \ Num.DF \ \ \ \ \ \ \ \ \ \ Den.DF \ \ \ \ \ \ \ \ \ Sample\ \ Ratio\ \ \ \ \ \ F-Stat \ \ \ \ \ \ \ P-value\\\\$

$\frac{\sigma_1^2}{\sigma_1^2} \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 15 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 15 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2.3478261 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 2.3478261 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 0.1091$

Test statistic $= 2.3478 \approx 2.35$

P-value > 0.10

The null hypothesis should not be rejected.
