Complete the triangle. Find all missing sides and angles. Round to the nearest tenth. Triangle DEF; DE=23 and FE=25 DF=?
Angle F=?
Angle E=?

help pls!!

DF= 9.8

Angle F= 42.6 degrees

Angle E= 23.1 degrees

Step-by-step explanation:

so for the sides we can use the pythagorean theorem

23^2+b^2=25^2

   23 squared is 529 and

   25 squared is 625

529+b^2=625

    subtract 529 from both sides

b^2=96

    the square root of 96 is ~9.8

b=9.8

To find the angles you use sin, cos, or tan. Now that we know all three sides it doesn't matter which one you use so... pick your favorite.

sinf=23/25

f= ~66.9 degrees

tane= 23/25

e= ~23.1

10 cm

step-by-step explanation:

if the polygon is a rectangle, then the perimeter is x+x+y+y. using the values that you gave, the perimeter is 3+3+2+2=10cm.
