You lost minus when you were adding two equations.
-176= - 22x -12y
<span>144 = 6x +12y
</span>-32= - 16x
x=2
88=11x+6y,
88=11*2+6y
6y=66
y=11
Check:
88=11x+6y=11*2+6*11=88 True
144=6x+12y=6*2+12*11=12+132=144 True

Answer:
the corresponding angles are equal in similar figures.
Step-by-step explanation:
When two figures are similar then the corresponding angles of the two figures are equal. the side of the figures are in proportional.
for example, when triangle ABC is similar to triangle DEF
then the corresponding angles are equal
<A=<D
<B=<E
<C=<F
so the corresponding angles are equal in similar figures.
41, 50, 59
all you have to do is subtract the first number from the second number which is 9. then you add 9 to the last number to get your answer
Answer:
75°
Step-by-step explanation:
firstly, use the pythagoras theorem
Square root(8²-2²) = 7.75
Then, use sine
sine A= 7.75/8
Sine A=0.9688
A= (sine power of -1) x (0.9688)
A=75.63
