Answer:
18617.66 ft^2
Step-by-step explanation:
sides of triangular base
 a=  145ft  , 
b = 257ft ,
c =  290ft
<u>calculate the area of the base  </u>
The base is a scalene triangle hence the area is calculated as follows 
s = ( a + b + c ) / 2
   = ( 145 + 257 + 290 ) / 2 = 346 
Area of triangle = 
                           = 18617.66 ft^2
 
        
             
        
        
        
Answer:
p= 50
Step-by-step explanation:
the angle that measures 130 is supplementary to the angle below, meaning the other angle must equal 50 degrees. This angle is an alternate interior angle with angle p, making them congruent.
 
        
             
        
        
        
Answer
<h2>
4</h2>
Step-by-step explanation:
Given,
r = 10
Let's create an equation,

plugging the value of r

Multiply the numbers

Move 5s to L.H.S and change its sign
Similarly, Move 30 to R.H.S and change its sign.

Calculate

The difference sign ( - ) should be cancelled on both sides

Divide both sides of the equation by 5

Calculate

The value of s is 4.
Hope this helps..

the length of a leg on a 45-45-90 triangle given the hypotenuse is half the length of the hypotenuse times sqrt(2)
hypotenuse = 10
 10/2 =5
 so the answer should be 5sqrt(2), which I don't see as a choice
