In triangle ABC we have
To find other sides and angles.
Use sine formula for triangles
Cross multiply to get
or
Angle B = 180-A-C
= or
b =18.84 or 16.44
There are two triangles
with
Step-by-step explanation: First equation: 3.4.1 3y + 7 = 4y
Subtract 3y from both sides: 3.4.1 (3y - 3y) + 7 - 3y = 4y - 3y
Simplify: 3.4.1 7 = 4y
Divide both sides by 3.4.1: 7 / 3.4.1 = 4 / 3.4.1 * y
Multiply both sides by y: 7y = 4 * 3.4.1y
Substitute 7y with LHS: 4 * 3.4.1y = 7 * Second equation: 3.4.2 10 - 3y + 4 = 8 + 4v - y
Add 3y to both sides: 3.4.2 (10 - 3y + 4) + 3y = 8 + 4v - y + 3y
Simplify: 3.4.2 17 = 12 + 4v
Subtract 12 from both sides: 3.4.2 (17 - 12) + 12 = 4v
Divide both sides by 3.4.2: 4.2 * 5 = 4v
Multiply both sides by v: 4.2v = 4 *

Answer:
5.83095
Step-by-step explanation:
X1= 6
X2= 1
Y1 = -2
Y2= -5
Distance Formula = √(X2-X1)²+ (Y2-y1)²
Step 1. calculate (X2-X1)²
(1 - 6)2 = 25
Step 2. calculate (Y2-Y1)²
(-5 - -2)2 = 9
Step 3. calculate √25 + 9
= 5.83095
