180 = y + y + 30 + 40
180 = 2y + 70
180 - 70 = 2y
110 = 2y
y = 110/2
y = 55
6 is in the ten millions place. The number next to 6 is 1, which is less than 5, so you round down. The nearest 10 million is 60,000,000.
Answer:
Step-by-step explanation:
m=10
Step-by-step explanation:
The angles ∠LHM and ∠JHM are on a straight line, therefore they are supplementary and add to 180 degrees
∠LHM+∠JHM=180
We know that ∠LHM is 2m+10 and ∠JHM is 5m+100, so we can substitute them in
2m+10+5m+100=180
Combine like terms
(2m+5m)+(10+100)=180
7m+110=180
Subtract 110 from both side s
7m=70
Divide by 7 on both sides
m=10

Answer:
"Haruto is correct because the angle is coterminal with 3pi/4 and the reference angle is pi/4."
Step-by-step explanation:
Coterminal angle:
Coterminal Angles are angles who share the same initial side and terminal sides. Finding coterminal angles is as simple as adding or subtracting 360° or 2π to each angle, depending on whether the given angle is in degrees or radians.
Finding if 3pi/4 is coterminal with 19pi/4:
19pi/4
= 16pi/4 + 3pi/4
= 4pi + 3pi/4
= 2(2pi) + 3pi/4
= 2(360°) + 3pi/4
= 3pi/4
Hence they are coterminal.
Reference angle:
The smallest angle that the terminal side makes with x-axis.
3pi/4 falls in second quadrant.
In 2nd quadrant, reference angle is given as = pi - 3pi/4
reference angle = pi/4.
