Answer:
option D; 20/3 OR 6 2/3
Step-by-step explanation:
CONVERT THE HOURS INTO MINUTES;
3/4 × 60 = 45 mins
1hour = 60 mins
45 mins = 5 miles
60 mins = ??
cross multiply;
60 by 5 ÷ 45 to get 20/3.
Answer:
x = -50
Step-by-step explanation:
2x+75=75-2x | Given
2x = -150 - 2x | Subtract 75 from both sides
4x = -150 | Add 2x to both sides
x = -50
Answer:
40
Step-by-step explanation:
In the triangle, there is a 90 degree angle and Angle 1 (what we are looking for) and the other angle, lets call is Angle 2.
Lets find Angle 2 first.
First of all, the angle between angle 40 and 90 can be found easily.
That angle (lets call it "x) and 40 and 90 make a straight angle (180 degrees). So we can write:
40 + x + 90 = 180
Lets solve for "x":
40 + x + 90 = 180
130 + x = 180
x = 180 - 130
x = 50
Now, This angle (50) and Angle 2 are same [vertical angles]
So,
Angle 2 = 50
Now, there are 180 degrees in 3 angles in a triangle. So for the triangle shown, we cacn write:
90 + Angle 1 + Angle 2 = 180
90 + Angle 1 + 50 = 180
Angle 1 + 140 = 180
Angle 1 = 180 - 140
<u>Angle 1 = 40</u>
