Answer: angle y is 50°
Step-by-step explanation:
t + 2t - 30 = 90
3t -30 = 90
3t = 90+30
t = 120/3 = 40 = angle X
Angle y = 2t-30
y = 2*40-30
=80-30 = 50
Answer:
Step-by-step explanation: x = 9
x = 3
Step by step solution :
Step 1 :
Trying to factor by splitting the middle term
1.1 Factoring x2-12x+27
The first term is, x2 its coefficient is 1 .
The middle term is, -12x its coefficient is -12 .
The last term, "the constant", is +27
Step-1 : Multiply the coefficient of the first term by the constant 1 • 27 = 27
Step-2 : Find two factors of 27 whose sum equals the coefficient of the middle term, which is -12 .
-27
