In a triangle, one side length is 4 feet and another side length is 7 feet. Which answers are possible lengths for the third side?
Answers
Answer:
3
Step-by-step explanation:
You might just think that I subtracted but on the triangle the last side is the base which is always smaller.
Answer: The answers are 4, 8, 10
To solve, you must use the Triangle Inequality Rule -
Subtract 7-4=3; therefore, the 3rd side must be greater than 3
Add 7+4=11; therefore, the 3rd side must also be less than 11
Any number greater than 3 or less than 11 would be correct.

Solve each compound iniquity and graph its solution.
Answers
Answer:
-6 < n < -4
Step-by-step explanation:
Solving the inequality 5 + 7n > -37 :
5 + 7n > -37
⇔ 7n > -37 - 5
⇔ 7n > -42
⇔ n > -42/7
⇔ n > -6
Solving the inequality n + 8 < 4 :
n + 8 < 4
⇔ n < 4 - 8
⇔ n < -4
Then , the solution to the compound inequality
5 + 7n > -37 and n + 8 < 4 is :
All real numbers n ,where -6 < n < -4
The solution in interval notation (-6 , -4)

Juan noticed that if he takes the opposite of his age and
adds 40, he gets the number 28: How old is Juan? Write
an equation and solve. Use a for his age.
Answers
Answer:
-a + 40 = 28, a = 12
Step-by-step explanation:
If he takes the opposite of his age, that means the current number is negative. We can get -a + 40 = 28, we can then simplify by subtracting both sides by 40 and getting -a = -12 which is equal to a = 12

i need help finding the value of x and the measure of each angle
Answers
Answer:
x=7, angle a= 45 degrees, angle b= 65 degrees
Step-by-step explanation:
All the angles in a triangle must add up to 180. Subtract 70 from 180, add both angle a and angle b to get 16x-2=110, solve for x, x=7. Substitute x out for 7 in the equations then simplify to get angle a=45 and angle b=65
Answer:
x = 7
m∠B = 65
m∠A = 45
Step-by-step explanation:
So we know that the inside of a triangle equals 180º. So we have one angle already, 70º, so what we can do is subtract 70 from 180.
180 - 70 = 110
Now we can set both equations equal to 110.
2 + 9x + 7x - 4 = 110
Now simplify.
2 + 9x + 7x - 4 = 110
2 + 16x - 4 = 110
16x - 2 = 110
+2 +2
------------------
16x = 112
÷16 ÷16
-----------------
x = 7
So now you can just plug 7 in for x to check your answers
2 + 9(7) = 65
7(7) - 4 = 45
65 + 45 + 70 = 180

WILL PICK BRAINLIEST! A line l has slope 2. What is the slope of line l1 if l1 ⊥ l ? What is the slope of l2 if l2 ∥ l ?
Answers
Answer:
1. The slope of line l1 is -1/2
2. The slope of l2 is 2
Step-by-step explanation:
Perpendicular lines have opposite inverse slopes. The inverse of 2 is 1/2 and the opposite is -2. Therefore the opposite inverse slope of the perpendicular line, l1, is -1/2
When two lines are parallel, the slopes are the same. l2 is parallel to l therefore, they share the same slope.

(screenshot included) I need to find TWO ways to get the area of the ABC triangle, I did the (base x height)÷2, so (9.6x3.6)÷2 and got 17.28, but I can't find any other way to solve this. PLEASE HELP
Answers
Answer: 17.28 cm^2
Step-by-step explanation:
You can also use AC as the base, then BE will be the height to that.
Assuming you want your answer in cm^2, then (7.2*4.8)/2 = 17.28 cm^2.
Answer:
2160mm
Step-by-step explanation:
Recall that to find the area of a triangle, you need to follow the formula:
A = 1/2 * b * h
But first we need to convert the cm to mm, or else our calculations will be incorrect:
9.6 cm = 96 mm
4.8 cm = 48 mm
Let's cut the triangle into two pieces to make it easier for us to find the area. We'll start with triangle ACD:
A = 1/2 * 36 * 72
A = 1/2 * 2592
A = 1296 mm
Now that we have the area for triangle ACD, let's move on to try to find the area of triangle DCB:
A = 1/2 * 36 * 48
A = 1/2 * 1728
A = 864
It's time to add them up:
(DCB) 864 + (ACD) 1296 = 2160
The area of the triangle is 2160 mm.
In the scale used on a blueprint, 1/5 inches represents 3 feet. On the blueprint, what is the length of a room with an actual length of 30 feet?
(You have to convert the fraction to a decimal first)
A. 6 in
B. 2 in
C. 1/2 in
D. 2 1/2 in
Answers
9514 1404 393
Answer:
B. 2 in
Step-by-step explanation:
The lengths are proportional, so you have ...
blueprint length / room length = (1/5 in)/(3 ft) = (x in)/(30 ft)
Multiplying by 30 ft gives ...
x in = (1/5 in)(30/3) = 10/5 in = 2 in . . . . . note that units of ft cancel
The blueprint length of the room is 2 inches.

Step-by-step explanation:
From the graph, we know the lengths of two legs.
a = 3
b = 7
Knowing this, we can use the Pythagorean Theorem to solve for c, the hypotenuse. (remember, a^2 + b^2 = c^2)
c = √a2 + √b2
= √(7)2 + √(3)2
= √49 + √9
