Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81
The answer to your question is... Supplementary angles!!
This is so because they would both add up to 180 degrees because they make a straight line!
I hope this helps!!
Answer:
152/15
Step-by-step explanation:
3 1/5=16/5
3 1/6=19/6
----------------
(16/5)(19/6)=304/30
simplify
152/15
To find slope you need to use the coordinates of two points on the line. If the coordinates are (x1, y1) and (x2, y2) do y2-y1 / x2-x1 to find the slope.
So far in the equation of a line, y=mx+b, you have the "m" which is the slope.
Plug in the slope, and the x and y values from one of the points and solve for b, which is the y intercept.
Here's an example if the coordinates are (1,4) and (2,6):
6-4/2-1 = 2/1 = 2
The slope is 2.
y = 2x + b
4 = 2(1) + b
4 = 2 + b
4-2 = 2-2 + b
2= b
The full equation is y = 2x + 2
As we know :
now let's plug the value of given terms :
- (5)³ = a³ + b³ + (3×3)(5)
