Answer:
100°
Step-by-step explanation:
The relevant relation for angle x is ...
x = (AB +DE)/2
and for angle y, it is ...
y =(AC -DE)/2
Using the second relation to write an expression for DE, we have ...
DE = AC -2y
In the first equation, this lets us write ...
x = (AB +(AC -2y))/2 = (AB +(2AB -2y))/2
2x = 3AB-2y . . . . . . . . . . . . . . multiply by 2
(2x +2y)/3 = AB = AC/2 . . . . . add 2y; divide by 3
AC = (4/3)(x +y) = (4/3)(60° +15°) . . . . multiply by 2, substitute known values
AC = 100°
In finding the sum of 2+5 you would go right on the number line, while in finding the sum of -2+(-5) you would go left on the number line
Answer:
probably
D because they're both the same shape it's just D is smaller.
Step-by-step explanation:
1.all three sides are equal
2.2 sides and their included angle are equal
3.A pair of angles and their included side are equal
4.2 corresponding angles and their non included side are equal.
5.the hypotenuse and 1 leg of a right triangle equal.
