<span>The triangles are similar because y=130 and there are three pairs of congruent angles. </span>
Answer:
75 degrees
Step-by-step explanation:
all added up is 180 on every triangle. 70+35=105. 180-105=75
9^2*4^4 is the correct answer I believe.
Answer:
equation 2into minus 3 into equation 1
8x+ 3y= -28
-3x-3y=18
----------------
5x=10
x =2
put value of y in equation 2
8 into 2+3y=-28
16+3y= -28
3y= -28+16
3y= -12
y= -4
