Because segments XY and XZ are of equal length, angle Y and angle Z must be congruent.
All inner angles must add to 180 degrees since it's a triangle.
70+70+x=180
140+x=180
x=40
Final answer: D
Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8
Let x = total distance he covered
3x/4 by bus
1/2 . x/4 = x/8 by jogging
the remaining distance = x/8 by walking
thus x/8 = 800ft
x = 8 . 800 = 6400ft
Answer: the answer is B. 90√2
Step-by-step explanation:
It is a 45 45 90 triangle and the hypotenuse is always the smaller side (x) root 2
Or x√2
Answer:
Hope that help the answer is 300
Step-by-step explanation he drives for 3 hours at a rate of 80 km per hour, multiply:
Now we need to find how far he goes in 45 minutes. There are 60 minutes in an hour, so write and simplify:
45 is three quarters of an hour, so multiply that by 80 km per hour:
Add the distances together:
At a rate of 80 km per hours, in 3 hours and 45 minutes, Tim drives 300 km.
Finito.
