Answer:
m∠ MNL = 78º
Step-by-step explanation:
<u>Arcs meassures </u>
mML = (11x - 5)º
mJK = (4x + 26)°
<u>Angle meassure</u>
m∠MNL = (10 x – 12)º
______________________
angle measure = average of arcs
m∠MNL = (mML+ mJK)/2
Replacing
(10x – 12)º = ((11x - 5)º + (4x + 26)° )/ 2
10x -12 = (15x + 21 )/2
10x - 7.5x = 10.5 + 12
2.5x = 22.5
x= 9
m∠MNL = (10 x – 12)º
= 90 - 12
= 78º
Hello there!
Start by asking yourself:"How to find the percentage of a number?"
We need to use the equation y = P% * x
In this case, the y is 20%
Y = P% * X
Y = 20% * X
Now we need to convert the percentage to decimal
P = 20%/100
P = 0.2
Then go back to the equation
Y= 0.2 * 5
Y = 1
The answer is 1
I hope the steps are easy to understand and hopefully the answer helps!
As always, I'm glad to help you today!
Answer:
10.31 ft
Step-by-step explanation:
the base is 25 ft²
leaves 100 ft² for the 4 sides on top
so each triangle got 25ft²
the base length of the triangle is 5ft, bc it's the base length of the pyramid
so the height of the triangle is 10ft,
bc only then do we get a surface area of 25ft²
(b * h /2) for the triangle
now that we got base length and height,
let's look for the slant
we recall the pythagoras stuff to get the missing side of the triangle. but notice that we need to split the triangle in half to get a 90° angle.
leaving us with 10ft (height) and 2.5ft
slant² = 10² + 2.5²
slant² = 106.25
slant = sqrt(106.25)
slant = 10.31
Answer:
15.6=c
Step-by-step explanation:
(12)^2+(10)^2=c^2
144+100=c^2
244=c^2
square root of both sides=244= square root c^2
15.620499=c
15.6=c
