Well, it says to use a calculator to calculate them. So a calculator I would highly recommend is the Desmos graphing calculator.
We know that
<span>applying the Pythagorean theorem
c</span>²=a²+b²
c is the <span>length of the diagonal
a=100 yd
b=130 yd
c</span>²=100²+130²-------> c²=26900---------> c=√26900 units----> c=10√269 units
the answer is
the length of the diagonal is 10√269 units or 164.012 units
Answer:
G (4 , -4)
Area CDEF : 176
Step-by-step explanation:
CD ⊥ x axis
FE ⊥ x axis
Point G (x , y) x = 4 and y = -4
G (4 , -4)
CD = 5 + 4 = 9
FE = 7 + 6 = 13
DG = 12 + 4 = 16
Area CDEF = (Cd + FE) x DG / 2 = (9 + 13) x 16 /2 = 176
4 degrees.
Divide 20 by 2 to get 10, subtract 6.
