I might be wrong but I think it’s 143 meters
Step-by-step explanation:
4y-10 and 3x are supplementary angles
so 4y-10+3x=180° (1)
4y-10 and 9x+12 are alternate exterior angles and because we have two parallel lines then these angles are congruent.
so 4y-10=9x+12 (2)
so we have
(1) 4y+3x=180+10
(2) 4y-9x=12+10
(1) 4y=190-3x
we replace this equation to the second equation
190-3x-9x=22
190-22=9x+3x
168=12x
x=168/12
x=14
4y =190-3*(14)=190-42=148
y=148/4=37
3x=3*14=42°
4y-10=4*37-10=148-10=138°
9x+12=9*14+12=126+12=138°
Answer:
12
Step-by-step explanation:
It is a scale. If 3=9 in this case. What times 3 equals 9?
3. So we multiply 3x4 to get 12.
Answer: j to the 13th Power
Step-by-step explanation:
Since J has been written 13 times it'll equal j to the 13 power
x^2 -3x+11=0
using the determinant
b^2-4ac
(-3)^2 -4(1)*11
9 -44
-36<0 it has no real solutions
