Answer: 7
Step-by-step explanation:
As tangents drawn from a common external point to a circle are congruent,
- 8x - 7 = 6x + 7
- 2x - 7 = 7 [subtract 2x from both sides]
- 2x = 14 [add 7 to both sides]
- x = 7 [divide both sides by 2]
Answer:
3 ft times<em> x </em>ft
Step-by-step explanation:
You don't know what the x is so you can keep it as a x.You are going to multiply it so it is 3 ft times<em> x </em>ft
Answer:
4/5
Step-by-step explanation:
Given :
- A right angled triangle with sides 24 , 3 and 40 .
And we need to find the value of sinZ .
We know that , sine is the ratio of perpendicular and Hypotenuse. So that ,
sinZ = p/h
sin Z = 32/40
sin Z = 4/5

<u>Answer:</u>
log7
<u>Step-by-step explanation:</u>
We are given the following expression in terms of log and we are to solve it:
log (14/3) + log (11/5) - log (22/15)
Just to recall, when we divide two values that have the same base, we basically subtract the exponents.
So applying this rule here to get:
(log11 - log5) + (log14 - log3) - (log22 - log15)
= log11 - log5 + log14 - log3 - log2×11 + log5.3
= loh11 - log5 + log14 - log3 - log2 - log11 + log5 + log3
Cancelling out the like terms to get:
= log14 - log2
= log 14/2
= log7
Absolute value of -3.25 is 3.25, so you will find it between 2.3 and 3.3 (D)
