Answer: 20°
Step-by-step explanation:
Let's call angle 1 x and angle 2 y
We know that x is three times greater than y, and that means that we can write it like this:
3y = x pls let me know if this part is confusing
Then we can write this entire equation:
3y + y = 80 remember, x = 3y
4y = 80
y = 20

What is the distance to the nearest tenth of a unit between point H ( -4,6 ) and point I ( 2,-3 )
Answers
Answer:
10.81 units
Step-by-step explanation:
Given data
point H ( -4,6 ) and point I ( 2,-3 )
x1= -4
y1=6
x2= 2
y2=-3
The formula for the distance between two points is
d=√((x_2-x_1)²+(y_2-y_1)²)
d=√((2-(-4))²+(-3-6)²)
d= √(2+4)²+(-9)²)
d= √(6)²+(-9)²)
d= √36+81
d=√117
d= 10.81 units
Hence the distance between the points is 10.81 units

You start at (6, 7). You move right 3 units. Where do you end?
Answers
Answer:
(9, 7) is where you would end
Step-by-step explanation:
We know that;
x-value = 6
y-value = 7
We also know that by moving 3 units right u will add 3 to the x-value, therefore;
Final x-value = 6 + 3 = 9
Final y-value = 7 (there is no change)
Final coordinates: (9, 7)

∠E and ∠F are vertical angles. If m∠E=(5x+55)° and m∠F=(11x-53)°, find m∠E
Answers
Answer:
145° = m∠E
Step-by-step explanation:
Vertical Angles: always congruent, therefore, to find Angle E first find "x" ;
5x + 55 = 11x - 53
55 = 6x - 53
108 = 6x
108/6 = x
18 = x
Now that we know x-value is 18, u can substitute that in for the equation for Angle E for "x";
=> 5(18) + 55 = m∠E
=> 145° = m∠E

The piper family arrived at the campground at the time shown on the clock. I took the family 2 hours and 15 minutes to get to the campground. What time did the family leave their house?
Answers
Answer:
As you included no picture, I do not know the time on the clock. We can however, work with assumed figures which you can then relate to your question.
Assuming the time on the clock was 10:45 am, if the family took 2 hours and 15 minutes to get to the camp ground, simply subtract this from 10:45 to find out what time they arrived.
Subtract the 2 hours from 10am:
= 10 - 2
= 8am
Subtract the 15 minutes from 45:
= 45 - 15
= 30
Put that together:
= 8:30 am
They left their house at 8:30 am using this scenario.
