Question

Find the Area of the Triangle *

Answer 1

Answer:

14

Step-by-step explanation:

first use the pythagorean theorem to find the length of the line adjacent to 4

4^2+x^2=5^2

16+x^2=25

x^2=9

x=3

then you can use the triangle area formula to find the area of the entire triangle

4*(3+7)*1/2=4*10*1/2=20

then, we find the area of the triangle that we need to subtract from the entire triangle

4*3*1/2=6

20-6=14
