The two triangles are similar.
The angles of a triangle sum to 180°. Using the known angles in the first triangle, we find the missing angle measure:
180-(65+70) = 180-135 = 45
We do the same for the second triangle:
180-(65+45) = 180 - 110 = 70
Any two triangles that have all 3 angles congruent is similar by AAA.
30 and 13
x-y=17 and x+y=43
x=17+y and x=43-y, so 17+y=43-y
so y=13
43-13=30, so x=30 and y=13
Answer:
The answer is 0.75x.
Step-by-step explanation:
If the dress is on sale for 25% off, then we know that the new sale price of the dress is x - (25/100)x = x - 0.25x = 0.75x.
0.15 in word form is fifteen hundredths
