Answer:
Step-by-step explanation:
6.
if they are similar ,then
8x+16=120
8x=104
x=13
7.
perimeter of Δ XZY=32+44+22=98
If they are similar then dilation=11/22=1/2
so perimeter of Δ BAC=98/2=49
So a triangle is always 180°.
If one angle is 90° then we can subtract that from the 180° to find out how much the other two will be.
180°-90°=90°
So the other two angles added together will have to equal 90°.
21 to the 4 power or you could also say 21^4 but they all equal the same thing hope it helps!
