Answer:
possible answers below!
Step-by-step explanation:
if they are vertical angles then the measure of ZB is 78
if they are supplementary then ZB is 102 degrees
if they are complementary then ZB is 12 degrees
It depends on where its located, cant really help if i dont have a pic..but i hope this helps! :)
Answer: Yochanan covered 5km by walking and 30 km by travelling on the bus.
Step-by-step explanation:
Let x represent the distance that Yochanan covered by walking.
Time = distance/speed
Yochanan walked from home to the bus stop at an average speed of 5km/h. This means that the time it took him to travel x km would be
x/5
The distance from his home to school is 35 kilometers. This means that the distance that he covered while travelling on the bus is 35 - x
He immediately got on his school bus and traveled at an average speed of 60km/h until he got to school. It means that the time that it took him to travel (35 - x) km would be
(35 - x)/60
If the entire trip took 1.5 hours, it means that
x/5 + (35 - x)/60 = 1.5
Cross multiplying by 60, it becomes
12x + 35 - x = 90
12x - x = 90 - 35
11x = 55
x = 55/11 = 5
The distance covered while travelling on the bus is
35 - 5 = 30km
Answer:
1) 3/4 = x
Step-by-step explanation:
1) 3/x -4 >0
=3/x -4+4>0 +4
=3/x> 4
switch 4 with x
x = 3/4
so literally the ans is x< 4
sorry but I don't know how to do the second question ☹️☹️
I <em />cant see what the numbers are but to find a cube, you do the number times itself 3 times example: 3 x 3 x 3 = 27. For cubing you do the number times itself twice for example 3 x 3 = 9.
I can see the square root though.
G: 36 = 6 64 = 8 81 = 9 25 = 5 324 = 18 529 = 23
The rest you should be able to understand with the explaining. Square root is finding what multiplied by itself is that number. Cube root is what times itself 3 times is that number. Hope this helps.
Answer:
x = 130 degrees
Step-by-step explanation:
let's imagine we move the point x further and further to the right (and move the connected lines with it) until we get a flat line that connects the two parallel lines.
in this case we have x = 180 degrees, and the top and bottom angles are both 90 degrees.
so, we have a total of all angles of 180 + 90 + 90 = 360 degrees.
this total had to stay the same no matter how we move x outward or inward.
so, even in the situation in the picture the sum of all 3 angles must be 360 degrees.
therefore we get
360 = 120 + 110 + x
360 = 230 + x
x = 130 degrees
