Answer:



Step-by-step explanation:
I will solve this question with the attached triangle
From the attachment, we have:



Required
Solve the triangle
First, we calculate
using sine law:

This gives:


Cross multiply


Divide both sides by 29

Take arcsin of both sides

Next, calculate
using:
--- angles in a triangle

Collect like terms


Next, calculate BC using sine laws

This gives:


Make BC the subject


Answer:
x=5/2
Step-by-step explanation:
Answer:
x=3
Step-by-step explanation:
4x−2(x−4)=−3+4x+5
4x+(−2)(x)+(−2)(−4)=−3+4x+5
4x+−2x+8=−3+4x+5
(4x+−2x)+(8)=(4x)+(−3+5)
2x+8=4x+2
2x+8−4x=4x+2−4x
−2x+8=2
−2x+8−8=2−8
−2x=−6
−2x
/−2
=
−6
/−2
x=3
