Answer:
A) x = 0 and x = 3π∕4
Step-by-step explanation:
cot 0° = oo (infinite)
4/3 x = 0
=> x = 0
cot 180° = oo (infinite)
4/3 x= 180
x = 3/4 × 180
= 135°
= ¾π
A die has six sides so you have a *blank*/6 chance of getting a certain number.
Since there are 3 even numbers on a die and 3 odd numbers. So the probability of rolling a even number would be:
3/6 or 1/2 or 50%
There is a one, one on a die so your chance of rolling a one the last time would be:
1/6 or about 16%
Hope this helps :) If you have any more questions just ask!
Answer:
a. x = 7
b. x = 36/5
Step-by-step explanation:
<u>Points to remember</u>
The ratio of of corresponding sides of similar triangles are equal.
<u>a). To find the value of x</u>
From the figure 1 we get two similar triangles, ΔABC and ADE
We can write,
AB/AD = AC/AE
3/6 = x/(x + 7)
3(x + 7) = 6 * x
3x + 21 = 6x
6x - 3x = 21
3x = 21
x = 21/3 = 7
<u>b). To find the value of x</u>
From the figure b we get
ΔABC ~ ΔEDF
AB/DE = BC/DF
4/5 = x/9
x = (4 * 9)/5 = 36/5
