Answer:
x = 45°
Step-by-step explanation:
"Isosceles" means the base angles are congruent: they both have the same measure, 45°. (The hypotenuse is the "base" for this isosceles triangle.)
The acute angles of a right triangle are complementary, so the third angle can also be found as 90° -45° = 45°.
Assuming the other is equal to x, this would be a 30-60-90 triangle. This is because those angles must add to 90 degrees and one must be 2 times the second.
Answer:
x+3y=-9
Step-by-step explanation:
-2(x+3y)=18
x+3y=18/-2
x+3y=-9
So 9 x 8 = 72
72/2 = 36
36 x 10 = 360
so 360in
Hope this helps
