I think it's B. The sum of angles in a triangle is always 180 degrees.
0.3x = 0.2 - 0.2x
0.5x = 0.2
x =0.2/0.5 = 2/5
Answer:
Value of given expression
when p = -4 and q = 2 is -4.
Step-by-step explanation:
Given expression ,
We have to evaluate the value of the expression when p = -4 and q = 2
Consider the expression given 
To find the value a the given value just put the values in the given expression
becomes 
Solve further to get its value,


Thus, value of given expression
when p = -4 and q = 2 is -4.
A = base side=3
b= base side=5
c = base side=3
h= height=7-4=3
l= lenght=6
w= width=5
h= height=4
V= 1/4h√(-a⁴+2(ab)²+2(ac)²-b⁴+2(bc)²-c⁴) + l w h
V=12.44+ 120=132.44 unit³
