X=82
it adds up to 180 so (x+6)+(x+10)=180
The coefficient is the number next to the variable so 9.
Answer:
k = 45
The angles are 45 , 45, 90
Step-by-step explanation:
The sum of the angles of a triangle are 180
45+ k+2k = 180
Combine like terms
45+3k = 180
Subtract 45 from each side
45+3k-45 = 180-45
3k = 135
Divide by 3
3k/3 = 135/3
k =45
The angles are 45, k,2k
The angles are 45 , 45, 90
Answer:
y = 3/2x + 7
Step-by-step explanation:
y - 1 = 3/2 (x + 4)
y = 3/2x + b
1 = 3/2(-4) + b
1 = -6 + b
7 = b
