Answer:
Step-by-step explanation:
The point-slope form of an equation of a line:
m - slope
We have
Substitute:
Convert to the slope-intercept form
<em>use the distributive property</em>
<em>add 3 to both sides</em>
Convert to the standard form
<em>multiply both sides by 3</em>
<em>add x to both sides</em>
Answer:
<em>1+√3</em>
Step-by-step explanation:
Area of the triangle = 1/2 * base * height
Area of the triangle = 1/2 * AC * BD
We need to get AC
AC = AD+DC
Get base AD using SOH CAH TOA
tan 45 = 4/AD
AD = 4/tan45
AD = 4/1
AD = 4
Get DC
tan 30 = 4/DC
DC = 4/tan 30
DC = 4/(1/√3)
DC = 4√3
AC = 4 + 4√3
AC = 4(1+√3)
Get the Area of the triangle
<em>Area = 1/2 * 4 * 4(1+√3)</em>
<em>Area of the triangle = 1+√3</em>
The correct answer is C plane HJG
