Update the question so it's on-topic for Mathematics Stack Exchange. Closed 4 years ago. How many words can be made by using the letters of the word ENGLAND such that words begin and end with a vowel? I couldn't understand how come the answer to this question is 120
Your answer for this is 17 hope i helped
Step-by-step explanation:
Four bought a book at $6
4 x $6 = $24
8 x $x = $8x
Expression
$24 + $8x
Answer:
x = 9
Step-by-step explanation:
Sum of all angles of a triangle = 180
63 + 7x + 6x = 180
63 + 13x =180
13x = 180 - 63
13x = 117
x = 117/13
x = 9
Answer:
22.96 cm
Step-by-step explanation:
Let the point of contact of the tangent with the circle be R.
Let the centre of the circle be O.
We are told that from Point P, the length of the tangent is 24 cm.
Thus, PR = 24 cm
Now, the radius will be perpendicular to the tangent at the point of contact with the circle.
Thus, ORP will form a right angle triangle where ∠R = 90°
Since radius = 7 cm, we can use pythagoras theorem to find OP which is the distance of P from the centre.
Thus;
OP = √(24² - 7²)
OP = √527
OP = 22.96 cm
