Answer:
here:given
PQ=17.4m
PR=7.6m
QR=?
NOW:QR^2=PQ^2-PR^2
QR=[(17.4)^2-(7.6)^2]^1/2
QR=[302.76-57.76]^1/2
QR=15.65
now: in tringle PKR
ANGLE PKR=43 DEGREE [180-137] IN TRINGLE ALL SIDES SUM 180]
tan(43)=PR/KR
Tan(43)=7.6/KR
KR=7.6/0.932
KR=8.15
NOW:QK=QR-KR
QK=15.65-8.15
QK=7.5
Answer:
Step-by-step explanation:
Given that each question after the first is worth 4 points more than the preceding question.
Total questions = 10
Let a be the marks for the first question.
Then the marks for 10 questions in order are a, a+4, a+8,....a+36
This is an arithmetic sequence with common difference d =4
Sum of 10 terms =
This sum is given as 360
Equating we get
Hence III question will have points as 18+2(4) = 26.
Answer:
1/6 of a cup
Step-by-step explanation:
You're trying to figure out what 1/3 subtract 1/2 is, right?
Well first, convert both of them so they both have the same denominator.
Common Denominator = 6
So, 1/3 is 2/6 and 1/2 is 3/6 and 2/6 plus 3/6 is 5/6. Well, what's left in the cup? 6/6 subtract 5/6 is 1/6
Hope that helps!
Answer:
20
Step-by-step explanation:
If lines m and n are parallel, then the labelled angles would be considered alternate exterior angles. By definition, such angles are of the same value.
Thus, we set the two expressions of 4x - 23 and 2x + 17 equal:
4x - 23 = 2x + 17
Subtract 2x from both sides and add 23 to both sides:
2x = 23 + 17 = 40
Divide by 2:
x = 40/2 = 20
The answer is thus 20.
