The answer is 152 because 9+10 is 19 and 2x4 is 8 so 19 x8 is 152
Q(-3,-3)
R(3,2)
S(5,2)
T(5,-4)
Answer:
x=3.4
y=-6.75
Step-by-step explanation:
5x+4y=-10 (equation 1 )
-5x+3y=-17 (equation 2)
7y=-27
y=-6.75
substitution (equation 1 ) y=-6.75
5x-27=-10
5x=17
x=3.4
The answer would be 20. Because the whole angle would have to be 90 so you already have 30 so that leaves you with 60 which you divide by 3 and gives you 20
