The 9 represents 90.....................
Answer:
5cm
Step-by-step explanation:
Find the diagram attached.
From ΔBCD, ∠BCD = 90-∠ACD
∠BCD = 90-60
∠BCD = 30°
Also tan60 = CD/BD
tan 60 = CD/5
CD = 5tan60
CD = 5√3 cm
Similarly from ΔACD, tan30 = CD/AD
tan30 = 5√3/AD
AD = 5√3/tan30
AD = 5√3/(1/√3)
AD = 5√3 * √3/1
AD = 5 cm
Hence the length of side AD is 5cm
Answer:
57 in

Answer:
3 3/5
Step-by-step explanation:
9/13 ÷5/26
We can use copy dot flip
Take the first number and copy it
9/13
Change the division to multiplication
9/13 *
Flip the second number
9/13 * 26/5
I will rewrite the fractions for easier cancellation
9/5 * 26/13
9/5 * 2/1
18/5
5 goes into 18 3 times 3*5 = 15 with 3 left over
3 3/5
Answer: The x intercept for Line A is 2 and the x-intercept for line B is -6.
Step-by-step explanation:
Line A uses the equation y = -1/2x + 1 and to find the x intercept y has to be zero so set the equation equal 0 and solve for x.
0 = -1/2x + 1 Subtract one from both sides
- 1 -1
-1 = -1/2x divide both sides by -1/2
x = 2
So the x intercept for A is 2
For Line B it already indicates the x intercept because that is when y is 0. So when y is 0 then x is -6.
