Answer:
x=65
Step-by-step explanation:
since this is an isosceles triangle the bottom 2 angles each equal 25 degrees
the big triangle = 180 y is the other angle in the big triangle
25+25 + y = 180
50 + y = 180
subtract 50 from each side
y =180-50
y= 30
now y is split into 2 equal angles x
y = 2x
130 = 2x
divide each side by 2
130/2 =2x/2
65 = x
1.89 * 10^12
1.89e +12
e is shorthand for *10^(
10 is the answer hope it’s right papa bless

Answer:
2.1+5.8-4.1
= 3.8
Step-by-step explanation:

Add 2.1 and 5.8 to get 7.9
7.9 - 4.1
subtract 4.1 from 7.9 to get 3.8
3.8
Factor
= 3 = 3.8
