Answer:
Height is 18 inches.
Base is 36 inches.
Step-by-step explanation:
Let the base of the triangular table top be x inches.
The height will be x inches.
The area of the triangular table top is 324 inches²
Area of a triangle = × Base × Height
342 inches² = × x × x
= 324
Finding the square root on both sides gives;
= 18
Therefore x (the base) = 36 inches
And (the height) = 18 inches.
Answer:
47.91 units²
Step-by-step explanation:
This can be solved using Heron's triangle (see attached)
in this case, your lengths are
a = 3+9=12
b=3+5=8
c=5+9=14
Hence,.
S = (1/2) x (a + b + c) = (1/2) (12+8+14) = 17
(s - a) = 17 -12 = 5
(s - b) = 9
(s - c) = 3
Area = √ [ s (s-a) (s-b) (s-c) ]
= √ [ 17 x 5 x 9 x 3 ] = √2295 = 47.9061 = 47.91 units² (rounded to nearest hundreth)
Answer:
Step-by-step explanation:
We are given that:
Where θ is in QIV.
And we want to find the value of tan(θ).
Recall that cosine is the ratio of the adjacent side over the hypotenuse.
Therefore, the opposite side is:
Next, in QIV, only cosine is positive: sine and tangent are both negative.
Tangent is the ratio of the opposite side to the adjacent. So:
Substitute. Tangent is negative in QIV. Hence:
Answer:
1) they equation they solved was correct as they were able to do the correct operation to yield their answer.
2)this problem should be approached by subbing in the correct X values and y values into their rightful position, by doing this U will yrild the correct answer
