Answer:
option a
Step-by-step explanation:
as 145 +10 = 155°
and total angle measure of triangle is 180
so
180-155 = 25°
in option a one angle is 10
other is 25 so obviously last angle will be 145
and same is in the triangle abc
one angle is 10 other is 145 and last is 25
both hve same measures thus are same triangles.
Good Morning!
Distance = rate x time
1/2 mile = R x 2/5 hour
1/2=2/5R
/2/5 /2/5
R=1/2 x 5/2
R=1 1/4
She can swim 1 1/4 per hour.
I hope this helps! :)

Answer:
x= 20
Step-by-step explanation:
The three angles add to 90 degrees
x+2x+x+10 = 90
Combine like terms
4x+10 = 90
Subtract 10 from each side
4x +10-10 = 90-10
4x = 80
Divide by 4
4x/4 = 80/4
x = 20
Tan(-180)=0 the answer is 0.
