The some of an Isosceles triangle is 180.
if vertex B = 130 degrees then the other two must be equal 50 degrees. so you divided 50 by 2 which equals 25.
in this case you have 2 points which equal 50. so you take the one which is the closest to 25. which is the last point. m<A = 20 and m<C + 30.
I hope this is right.
Given:
<span>∠SRT ≅ ∠STR,
m∠SRT = 20,
m∠STU = 4x
Since </span>∠SRT ≅ ∠STR, then m∠STR = 20.
m∠STR + m∠STU = 180°
20 + 4x = 180
4x = 180 - 20
4x = 160
4x/4 = 160/4
x = 40
The value of x is 40.
I hope this is what you're looking for.
Answer:
x = 84
Step-by-step explanation:
The two angles form a line
A line is 180 degrees
x+11 +85 = 180
Combine like terms
x+96 = 180
Subtract 96 from each side
x+96-96 = 180-96
x = 84
We have 225 boxes. And each crate can handle 9 boxes.
Let x = the number of crates to be loader.
9x = 255
Divide both sides by 9
x = 25
