Answer:
82.4 cm
Step-by-step explanation:
The computation of the height is given below:
As we know that each right triangle contains the top angle of 20 degrees
So, the right angle & the bottom corner angle equivalent to
= 180 - 90 - 20
= 70 degrees
Now the height is
tangent = opposite leg ÷ adjacent leg
tan (70°) = height ÷ 30 cm
height = 30 cm × tan (70°)
= 82.4 cm
Short answer: B
Remark
A 45 degree angle means that the height is the same length as part of the base. But which part?
Givens
b1 = 9 feet
b2 = 23 feet
and the 45 degree angle on the right.
Determine the height.
The part of the base that is associated with the 45 degree angle is found by subtracting b1 from b2
b2 - b1 = 23 - 9 = 14
So 14 is also the height
Find the Area
A = 1/2 (b1 + b2)*h
b1 = 9
b2 = 23
h = 14
Area = 1/2(9 + 23) * 14
Area = 1/2 (32) * 14
Area = 16 * 14
Area = 224 <<<< answer
There's only one solution...the one you get when you divide both sides by 22 to solve for x. 902/22 = 41. That exponent on the x, the one you don't see, is a "1" which tells us that there is only 1 solution to this problem. If your x is squared, then you have 2 solutions; if it's cubed, you have 3, etc.
Answer:
-2/5
Step-by-step explanation:
The solution comes rom the formula for finding the slope of a graph: Rise/Run
In this case, the rise would be -2, because it is going down the graph 2 points. The run would be 5, because it is going to the right 5 points. Hopefully this will help you in the future.
