Both triangles are similar. The area of the larger triangle is about 382 ft2. Which is the best approximation for the area of th

melisa1 [442]

Answer: SECOND OPTION

Step-by-step explanation:

You must find the ratio of the sides of the triangle, as following:

$r=\frac{30}{42}=\frac{5}{7}$

Therefore, the ratio of the areas is:

$r_A=(\frac{5}{7})^{2}\\\\r_A=\frac{25}{49}$

Now you must multiply the area of the larger triangle by the ratio obtained above, therefore, you have that the result is:

$A_s=(382ft^{2})(\frac{25}{49})=194.89ft^{2}$ ≈ $195ft^{2}$

Triangle ABC has the following characteristics. Angle A is right angle. AB=8. AC= 15. Find BC

Novay_Z [31]

Answer is c
use pythagorean
a^2 + b^2 = c^2

8^2+15^2= c^2
289=c^2

sqrt both sides

c=17

BC=17
