Two angels in a triangle add up two 115 degrees what is the size of the third angle

1 answer:

5 0

The internal angles in a triangle add up to 180
I think the question should say
'2 angles in a triangle add up to 115 degrees'
so therefor
x+y+z=180
2 angles are x+y
115+z=180
z=3rd angle

solve
115+z=180
subtract 115 from boths ides
z=65

answer is third angle=65 degrees

A train traveled 63.75 miles at a rate of 85 miles per hour. Which equation can be used to find h, the number of hours it took t

sashaice [31]

Answer: 63.75 = 85h

Solving gives 0.75 hours.

Step-by-step explanation:

we now that speed = distance / time

therefore time will be Distance / speed

Given that distance = 63.75miles

Speed= 6=85miles per hour

Time(h) = 63.75miles/ 85.---- equation 1

But from the options given, the equation that can also be used to find number of hours is

63.75 = 85h

such that making h subject of formula still give us

h= 63.75/85 as in equation 1 above

solving gives that Time ( h) = 0.75 hours .
