Answer:
35i+13j
Step-by-step explanation:
Vector a = 9i+9j
Vector b = -4i+7j
We need to find the value of 3a-2b.
3a = 3(9i+9j) = 27i+27j
2b = 2(-4i+7j) = -8i+14j
3a-2b = 27i+27j-(-8i+14j)
= 27i+27j+8i-14j
= 35i+13j
Hence, the required vector is equal to 35i+13j.

Answer:
Step-by-step explanation:
sum of angle of triangle is 180 degree
5x+8x+50degree =180 degree
13x= 180-50
13x= 130
x= 130/13
x=10
5x= 5*10=50degree
8x= 8*10 =80degree
