Answer:

x=15 degrees

Step-by-step explanation:

The given triangle is isosceles, so both base angles are both (3x+18).

We also know that angles on a line add up to 180 degrees, so

(3x+18) + (8x-3) = 180 degrees

Simplify

11x + 15 = 180 degrees

11x = 180-15 = 165

Divide by coefficient on left-hand side

x = 165/11 = 15 degrees.

Elodia [21]

Answer:

Concept: Linear Algebra

Given two linearly independent vectors w and z
We want -w-z
Hence apply a negative gradient to w
w=-<-5,3> =<5,-3>
So <5,-3>-<1,4> = (<5-1>,<-3-4>)
The answer is <4,-7>
