Answer:
x = 19
Step-by-step explanation:
the question tells you that the angle CBD is 90°.
so, that means that angle DBE and angle CBE add up to 90.
using this, you can make the following equation:
2x - 1 + 5x - 42 = 90
2x + 5x + -43 = 90
7x - 43 = 90
add 43 to both sides
7x = 90 + 43
7x = 133
x = 133/7
800
3/4*3.14*(14/2)^3 = 807.77
X=x=−5y/3
y=x=−5y/3
2x+y/3⋅1/x−3y=1/3⋅1/2=x=−5y/3
